The Minneapolis–St. Paul area once had an extensive network of streetcars (operated for many years by Twin City Rapid Transit, a precursor of Metro Transit), but the tracks were removed and services were eliminated in the 1950s.
Over the years since the last trolley ran in 1954, many people have pushed for the reintroduction of rail transport in the Twin Cities. Proposals for a modern streetcar or light rail along the Hiawatha Avenue corridor appeared in the pages of the Star Tribune as early as 1974.The primary reason is that traffic congestion has grown considerably since the streetcar system ceased operation: a 2003 report by the Texas Transportation Institute indicated that the area was the 17th most congested area in the country, with the second fastest congestion growth.
Rail projects struggled to gain political support until the 1990s, when several factors combined to make the idea more palatable. Governor Jesse Ventura and Minnesota Transportation Commissioner Elwyn Tinklenberg heavily promoted the idea of rail transport, and significant amounts of money became available from the federal government. Previous governors had advocated light rail, but had not been able to get legislation passed. Governor Tim Pawlenty had campaigned on a promise to fight the expansion of light rail, but altered his opinions after taking office. He also initially opposed the Northstar Line commuter rail project, which is a rail corridor north of Minneapolis, but changed his mind about that project in January 2004 when a scaled-back version was shown to have good potential.
For many, the Hiawatha Avenue corridor was not the top choice for a new project. Popular other options included connecting Minneapolis with the western suburbs, though probably the most-desired option has been the Central Corridor connecting the Twin Cities themselves (Minneapolis and St. Paul) with a route down the middle of Interstate 94 or University Avenue. However, much of the land had already been acquired by the state in the 1960s to build a sunken radial expressway into downtown that was never built. In addition to the available land, the desire to connect to the airport and at least reach the vicinity of the Mall of America proved to be the bigger draw for decision-makers.
The idea of running a rail line down Hiawatha Avenue had already been around for at least a decade by the time the decision was made to go forward. In 1985, the Minnesota Department of Transportation (Mn/DOT) had produced an Environmental Impact Statement that concluded that light rail was the best alternative for the corridor. In 1996, the document was examined again as Mn/DOT looked at the possibility of adding bus rapid transit along the road, but money for light rail became available soon after, leading to the current layout.
Groundbreaking for the line took place on January 17, 2001. Regular service began on the first phase of the line on June 26, 2004, with the second phase opening later that year on December 4. Each opening was accompanied with two days of free rides on the train and area buses. The line was tested for months before opening, with regular service simulated for about a month before each phase went online. The Hiawatha Line opened exactly 50 years and one week after the last regular-service streetcars ran in the city.
Busways are still being examined for many future projects and it appears likely that at least one will be built. Construction of the area's second light rail line, the Green Line connecting downtown Minneapolis and St. Paul began in late 2010 and opened on June 14, 2014. On April 26, 2011, the U.S. government announced $478 million in funding for its construction.
During Super Bowl LII on February 4, 2018, hosted at U.S. Bank Stadium, the Blue Line was restricted to ticketholders and ran with non-stop service between a security checkpoint at the Mall of America and the stadium station. Service at other stations was replaced with free shuttle buses.
In March 2004, the labor union representing Metro Transit bus workers went on strike. This delayed the opening of the line from the anticipated start date of April 3, although there was some indication that the opening would have been delayed anyway. Apparently, some of the delay had to do with slow delivery of trainsets from Bombardier. Certain aspects of the design had been tried before, but the cars were the first to combine the factors of conforming to American standards (as opposed to European), having low floors and being built at the company's Mexico plant. Some problems also cropped up during testing of the vehicles, but Bombardier said that the issues were not out of the ordinary.
When the buses began rolling again on April 19, the line's opening was rolled back to June 26. Testing of the track and vehicles continued during the bus strike, as much of the work was performed by Bombardier employees rather than Metro Transit workers. Train operators who had already gone through the training process were given refresher courses when the strike ended.
An extension of the line to Brooklyn Park is planned. On August 3, 2020, after years of disagreements with The Burlington Northern Santa Fe (BNSF) Railway Company regarding use of BNSF's right-of-way, Metropolitan Council announced they would begin to "explore opportunities to advance this critical project without using BNSF Railway right of way."
On March 11, 2021, the Metropolitan Council and Hennepin County released revised potential route options for the proposed Blue Line Extension. The proposed new routes retain the northern part of the original alignment, but offer different routes through north Minneapolis, and (unlike the original plan) bypass the suburb of Golden Valley.
By January 2015, there had been 11 deaths from accidents on the line, eight of them pedestrians.
With an impending line expansion, Metro Transit rolled out a new rail safety campaign, with representatives of Metro Transit customers visiting schools and organizations situated near the Blue Line to discuss rail safety. The campaign won a visual design award from the Minnesota Association of Government Communicators.
By January 2016, two more people were killed in separate incidents on the Blue Line, one a bicyclist and one a man in a wheelchair, bringing the total number of deaths since opening to 13. In response, signs saying "See Tracks? Think Train" were added at locations of recent deaths along the Blue Line and Green Line (which, as of October 2018, has killed six people since its operation began in June 2014).
On April 10, 2018, a male bicyclist was struck and killed, making it the 14th death on the line. He was later identified as 39-year-old Colin Brougham of Minneapolis.
On September 2, 2019, a male bicyclist was struck and killed at the E. 35th St intersection, making it the 15th death for the line's history.
Additionally, there has been concern over violent assaults, robberies, and disorderly conduct that occurs on the station platforms while people wait for the trains. There was a murder by stabbing at the Lake Street/Midtown station in December 2014. Aggravated assaults, which involve the use of a weapon to cause serious injury, continued to increase through 2019 including another murder by stabbing at the Lake Street/Midtown station in October 2017. In January 2020, the Met Council approved $1.3 million in spending to install new 360-degree 4K resolution cameras on all Metro Transit light rail cars by the end of 2020.
In the early hours of January 23, 2020, a man was stabbed by another man during an altercation inside a northbound train car that had just left the Mall of America station. When the train arrived at the 28th Avenue Station in Bloomington, the suspect was arrested and the victim was taken to a local hospital, where he later died.
The Airport Line (formerly the R1 Airport) is a route of the SEPTA Regional Rail commuter rail system in Philadelphia, Pennsylvania, which officially runs between Philadelphia International Airport through Center City to Temple University station. In practice, however, only a few trains originate or terminate at Temple; most are through routed with lines to the north, primarily the Warminster Line, with some through-routed trains originating and terminating at Glenside.
The line between Center City and the airport runs seven days a week from 5:00 AM to midnight with trains every 30 minutes. The trip length from Suburban Station to the airport is 19 to 24 minutes. The line is fully grade-separated in the normal service, but one crossing between Temple University and Glenside is present at Rices Mill Road in Glenside.
While geographically on the former Pennsylvania Railroad side of the Regional Rail System, the route consists of new construction, a reconstructed industrial branch of the former Pennsylvania Railroad, and a shared Conrail (formerly Reading Company) freight branch. The Airport Line opened on April 28, 1985, as SEPTA R1, providing service from Center City to Philadelphia International Airport. By its twentieth anniversary in 2005, the line had carried over 20 million passengers to and from the airport. The line splits from Amtrak's Northeast Corridor north of Darby and passes over it via a flying junction. West of the airport, the line breaks from the old right-of-way and a new bridge carries it over I-95 and into the airport terminals between the baggage claim (arrivals) and the check-in counters (departures).
The line stops at four stations which are directly connected to each airport terminal by escalators and elevators which rise one level to the walkways between the arrival and departure areas. All airport stations feature high-level platforms to make it easier to board and alight from the train with luggage. Some stations can be accessed directly from the arrivals concourse by crossing Commercial Vehicles Road. The line ends between Terminals E and F at their combined station.
, most weekday Airport Line trains are through routed with the Warminster Line and alternate between terminating in Glenside and Warminster. Most weekend trains either continue on to Warminster or terminate at Temple University.
The Airport Line makes the following station stops, after leaving the Center City Commuter Connection.
Infill stations were planned from the beginning of service, two of which were on the Airport Line proper: one at 70th Street, the other one at 84th Street. The latter station was opened in 1997 as Eastwick, while 70th Street was never built, and has since disappeared from maps. Additionally, University City station (proposed as "Civic Center", now Penn Medicine station) opened in April 1995 to serve all R1, R2 and R3 trains passing it. All these stations appeared on 1984 SEPTA informational maps, the first ones to show the Center City Commuter Connection and the Airport Line.
SEPTA activated positive train control on the Airport Line on October 10, 2016.
Between FY 2008-FY 2018 annual ridership on the Airport Line peaked at 2,457,743 during FY 2015, but fell to 1,902,127 by FY 2018.
AirTrain is a fully automated people mover at San Francisco International Airport (SFO) that opened on February 24, 2003. It operates 24 hours a day on two separate lines, covering a total of . The service is free of charge, funded by a $20 "airport fee" charged by rental car companies. The system is located outside of the sterile area of each terminal, meaning passengers must exit and re-enter through a security checkpoint when using AirTrain to travel between terminals.
AirTrain operates on two lines—Red Line and Blue Line—both of which run every minutes. The Red Line travels in a clockwise loop, beginning with Garage G station and ending with Garage A station, which takes about 9 minutes to complete. The Blue Line travels in a counterclockwise loop, serving the same stations in reverse order, and also proceeding to West Field Road, the Rental Car Center, and long-term parking, which takes 25 minutes for a round trip.
A $15 million infill station was constructed to serve the Grand Hyatt at SFO, a new airport hotel. The hotel opened on October 7, 2019.
From 2003 to 2021, AirTrain did not provide access to SFO's long-term parking garage and lots; instead, passengers had to take a free airport shuttle bus between the airport terminals and the long-term parking areas. The former end of the track past the Rental Car Center station was only about away from the airport's long-term parking garage; an extension to the garage began service in May 2021, replacing the shuttle buses. The extension is estimated to eliminate previously driven by the shuttle buses each year.
The AirTrain stations at the International Terminal are located one level above ticketing, at both ends of the main hall. Stations at Terminals 1, 2, and 3 are located on level 5 of the domestic parking garage and can be accessed from mezzanine-level skybridges located near security checkpoints B, D, and F. The Garage A and G stations are accessible from level 7 of each garage. The long-term parking station is connected by a skybridge to level 5 of the long-term parking garage.
The AirTrain system was built by Bombardier Transportation at a cost of US $430 million and is composed of 38 Innovia APM 100 cars coupled in trains of up to three cars. The APM 100 cars can also be found at airports in Tampa, Denver, Atlanta, Seattle-Tacoma, Houston, and Madrid. They are operated automatically under Bombardier's Cityflo 650 CBTC (communications-based train control) signaling technology, making it one of the first radio-based train control systems to enter service.
The entire AirTrain fleet is accessible and allows rented baggage carts on board.
The Airport Development Plan from 2016 forecasts that ridership on the two lines will be over capacity in the future (42% and 87% over capacity on the Red and Blue Lines respectively) and recommends upgrades that would increase capacity. Specific upgrades include acquiring 30 additional AirTrain cars, upgrading existing stations to accommodate 4-car trains, and upgrading the maintenance facility to accommodate additional vehicles.
The Blue Line is a planned light rail line for connecting Austin–Bergstrom International Airport with the downtown Austin, Texas area in the United States. It is still in the planning stages as a part of Capital Metro's Project Connect. It is estimated to begin revenue service as early as 2028.
Austin's 2013 East Riverside Corridor Plan called for high-capacity transit to be installed along East Riverside Drive. This became part of the original Blue Line, which failed to find support in 2014 and was shelved. The Gold Line was formed from a segment of this original proposal, and is expected to be built as a separate bus rapid transit line.
In 2018, Capital Metro announced a new long-range planning project entitled Project Connect that outlines several major transit corridors consisting of commuter rail, light rail, and bus rapid transit. The Blue Line corridor will include a transit pathway for a light rail or bus rapid transit line running on the west side of Downtown Austin to Austin–Bergstrom International Airport in southeast Austin. The line was included as part of the Project Connect referendum during the 2020 United States presidential election.
South to north, from Austin–Bergstrom International Airport to the North Lamar Transit Center.
The MIA Mover is an automated people mover (APM) system which opened at the Miami International Airport (MIA) in metropolitan Miami, Florida, United States on September 9, 2011. The MIA Mover is designed to quickly transport landside passengers between Miami International Airport's Main Terminal and the Miami Intermodal Center (MIC). The MIA Mover is one of three separate automated people movers operating at the airport. The others are the Skytrain, which operates within Concourse D, and the MIA e Train people mover connecting Concourse E's satellite building.
In 2007, construction of a people mover instead of an extension of the existing Metrorail system to the airport became the preferred option for local authorities to provide greater connectivity to the airport terminals (Metrorail will connect at Miami Airport Station). On March 2, 2009, ground was officially broken for the project. Projected to transport 48,000 daily visitors by 2020, the MIA Mover construction utilized design-build methods and was paid for from a combination of revenue from the Miami-Dade Aviation Department’s Capital Improvement Program and the Florida Department of Transportation (FDOT).
In May 2012, MIA Mover suffered a minor derailment, and a breakdown in July 2017 required riders to walk along the tracks escorted by fire fighters.
Costing an estimated $259 million to complete, the link travels east from the MIA Station, to Central Boulevard and finally to NW 21st Street, where it curves north into the MIC Station. The ride lasts approximately three minutes. The concrete guideways are generally elevated an average of above grade and are supported by concrete piers every . The vehicles used are Mitsubishi Heavy Industries Crystal Movers (The same model also operates on the Skytrain in Concourse D).
The MIA Mover has two stations: the MIC Station and the MIA Station.
The MIC Station is the eastern terminus of the line located on the fourth floor of the MIC. The station contains direct access to the MIC's rental car center and Miami Airport Station where connections can be made to Metrorail, Tri-Rail, buses and taxicabs. The station is being constructed by FDOT.
The MIA Station is the western terminus of the line located on the third floor of the main terminal building between the Flamingo and Dolphin Parking Garages. Constructed by MDAD, a storage and maintenance facility for the APM vehicles is located beneath the MIA Station.
The Gold Line is a rapid transit line in the MARTA rail system. It operates between Doraville and Airport stations, running through Doraville, Chamblee, Brookhaven, Atlanta, East Point and College Park.
The Gold Line was previously called the Northeast-South Line until MARTA switched to a color-based naming system in October 2009. The North-South Line, from its launch, was considered one line, denoted with an orange color on old system maps until 2006 when the North Branch and the Northeast branch were redesignated as the North-South Line (the current Red Line) and the Northeast-South Line (the current Gold Line). Technically, with the 2009 designation change, there is no longer a mention of the color orange for the line. Using the Five Points station as a reference point, the Northeast Line was designated for trips headed to Doraville, and the South Line was designated for trips headed to the Airport.
Now known as the Gold Line, it shares trackage with its counterpart, the Red Line, between Airport and just north of the Lindbergh Center.
The Gold Line runs above ground, at-grade and below ground in various portions of its route. It begins at the northeastern terminus, Doraville station in Doraville. The nonrevenue tracks extend northeastward from the station north of I-285. It then goes southwestward paralleling Peachtree Road in DeKalb County. Upon entering Atlanta in Buckhead, it crosses "over" the Red Line in the median of GA 400 before joining the Red Line, going southwest paralleling I-85. It turns south through Midtown and enters downtown Atlanta, where it meets the Blue and Green Lines at Five Points station. Leaving downtown, the Gold Line continues south, paralleling Lee Street and Main Street into East Point and College Park before reaching its terminus at the Airport station.
When the color-based name change was proposed, it was the Yellow Line at first. However, in February 2010, the name was revised to Gold in order to address a concern among the Asian-American residents along the rail corridor. The section of the Gold Line that is not shared by the Red Line has a significant number of Asian-American residents, to whom the term "yellow" is considered derogatory. Despite the color name change, interestingly many MARTA system maps denoted the Gold Line with the yellow color still until 2017.
The Blue Line is a rapid transit line of the Washington Metro system, consisting of 27 stations in Fairfax County, Alexandria and Arlington, Virginia; the District of Columbia; and Prince George's County, Maryland, United States. The Blue Line runs from Franconia–Springfield to Largo Town Center. The line shares tracks with the Orange Line for 13 stations, the Silver Line for 18, and the Yellow Line for six. Only three stations are exclusive to the Blue Line.
All Blue Line service has been suspended between February 13, 2021 and May 23, 2021 due to platform reconstruction at and . Shuttle buses are provided to the closed stations.
With the formation of WMATA in October 1966, planning of the system shifted from federal hands to a regional body with representatives of the District, Maryland and Virginia. Congressional route approval was no longer a key consideration. Instead, routes had to serve each local suburban jurisdiction to assure that they would approve bond referenda to finance the system.
The Virginia portion of the Blue Line took much of its present form along the Richmond, Fredericksburg and Potomac Railroad right-of-way to Colchester, as construction along existing right-of-way is the least expensive way to build into the suburbs. A surface-level section of the Blue Line that parallels Virginia State Route 110 where passing Arlington National Cemetery and traveling between The Pentagon and Rosslyn replaced a section of the closed Rosslyn Connecting Railroad, a subsidiary of the Pennsylvania Railroad. The railroad's predecessor, the Washington Southern Railway, constructed the section in 1896 within the grade of the old disused Alexandria Canal.
Service on the Blue Line began on July 1, 1977, on 18 stations between National Airport in Arlington and Stadium-Armory in Washington – the first link of the Metro to Virginia. The line was extended by three stations to Addison Road on November 22, 1980. Service south of National Airport began on June 15, 1991 when Van Dorn Street opened. The original plan for the line was completed when this link was extended to Franconia–Springfield on June 29, 1997. Two new stations in Maryland – Morgan Boulevard and Largo Town Center – opened on December 18, 2004.
From its opening on November 20, 1978, until December 11, 1979, the Orange Line was co-aligned with the Blue Line from National Airport to Stadium-Armory, with the Orange Line continuing east from Stadium-Armory to New Carrollton. Beginning December 1, 1979, the Orange Line diverged westward from Rosslyn to Ballston. The Blue and Orange Lines remain co-aligned from Rosslyn to Stadium-Armory and the Silver Line is co-signed along the same route as well.
The Blue Line was originally planned to follow a slightly different route. The plan would have sent Blue Line trains to Huntington, with Yellow Line trains serving Franconia–Springfield. This was changed due to a shortage of rail cars at the time of the completion of the line to Huntington. Because fewer rail cars were required to operate Yellow Line service than would be required to run Blue Line service out to Huntington – due to the Yellow Line's shorter route – the line designations were switched. From 1999 to 2008, the Blue Line operated to Huntington on July 4, as part of Metro's special Independence Day service pattern.
The ARS had the Blue Line end at Addison Road. However, sports fans continually argued for a extension to the Capital Centre sports arena in Largo, Maryland. On February 27, 1997, the WMATA board approved construction of the extension. By the time the extension opened in 2004, professional basketball and hockey had relocated to a new arena atop the Gallery Place Station and the Capital Centre was replaced with a shopping mall. However, the extension still drew considerable sport spectator traffic because it is within walking distance of the FedExField football stadium. The extension cost $456 million.
In 1998, Congress changed the name of the Washington National Airport to the Ronald Reagan Washington National Airport with the law specifying that no money be spent to implement the name change. As a result, WMATA did not change the name of the National Airport Station (which never included the full name of the airport). In response to repeated inquiries from Republican congressmen that the station be renamed, WMATA stated that stations are renamed only at the request of the local jurisdiction. Because both Arlington County and the District of Columbia were controlled by Democrats, the name change was blocked. Not until 2001 did Congress make changing the station's name a condition of further federal funding.
In May 2018, Metro announced an extensive renovation of platforms at twenty stations across the system. To accommodate these platform reconstructions, Blue and Yellow Lines south of Ronald Reagan Washington National Airport would be closed from May to September 2019, in what would be the longest line closure in Metro's history. All trains terminated at Ronald Reagan Airport as a result.
From March 26, 2020 until June 28, 2020, trains were bypassing , , , , , and stations due to the 2020 coronavirus pandemic. All stations (except Arlington Cemetery) reopened beginning on June 28, 2020. Arlington Cemetery station was later reopened on August 23, 2020.
Beginning on November 27, 2020 until March 14, 2021, Blue Line trains began serving and stations during most weekends due to Metro modernizing the signal system at Alexandria Rail Yard causing both and Van Dorn Street stations to be closed. Additionally, trains operated to Huntington between December 20, 2020 and January 3, 2021 due to a full closure at Alexandria Rail Yard. Metro choose to do a full shutdown instead of single tracking because completing the same work with weekend single tracking could more than double the time for completion, while providing severely limited rail service with waits up to 36 minutes between trains. However work was completed three weeks earlier.
On December 14, 2020, WMATA announced that Blue Line service will be suspended between February 13 to May 23, 2021 in order to rebuild the platforms at both and . Additional Yellow Line trains will operate between and while Silver Line trains will serve in part of the Blue Line.
In terms of WMATA's internal route designations, the Blue Line service travels along the entirety of the J Route (from the terminus at Franconia-Springfield to the C & J junction just south of King Street), part of the C Route (from the C & J junction just south of King Street to Metro Center), part of the D Route (from Metro Center to the D & G Junction just east of Stadium-Armory) and the entire G Route (from the D & G junction past Stadium-Armory to the terminus at Largo Town Center). The Blue Line needs 23 six-car trains (138 rail cars) to run at peak capacity.
On June 18, 2012, Metro initiated its "Rush+" service plan, which had been under consideration for some time. This plan was intended to clear congestion at Rosslyn Station, where the Blue and Orange lines meet and ultimately prepare the tracks to accommodate the Silver Line. Under the plan, Blue Line trains continued on the usual route but some Yellow Line trains originated at Franconia–Springfield and were routed over the Fenwick Bridge to Greenbelt. During rush hour there were fewer Blue Line trains on the tracks which could mean potentially increased wait times for regular Blue Line customers. Furthermore, some Orange Line trains were routed to Largo Town Center until the Silver Line opened in 2014.
In addition, a transportation planning group has proposed an extension of the Blue Line that would reach Potomac Mills in Prince William County.
The following stations are along the line, from southwest to east:
The K Line (known as the Crenshaw/LAX Line during planning) is an under-construction light rail line that will run through southwest Los Angeles, in a north to south direction. It will connect the Crenshaw neighborhood and Leimert Park to the City of Inglewood and Los Angeles International Airport (LAX). When completed, the line will be a part of the Los Angeles County Metro Rail System and operate in an L shaped pattern along the current C Line between Norwalk and Aviation/LAX then on the new infrastructure to Expo/Crenshaw.
The project is being built by Los Angeles County Metropolitan Transportation Authority (Metro). The project has been given high priority by Metro in its long-range plan; it has funding set aside in Measure R. The Final EIR was certified on September 22, 2011. The Federal Transit Administration (FTA) gave its approval to build the $1.766 billion light rail line in January 2012.
Metro began pre-construction in July 2012, and a Notice to Proceed was issued by Metro in September 2013. An official ground-breaking ceremony for the project was held on January 21, 2014. Heavy construction began in June 2014 and initial revenue service was projected to begin by mid-2020. , the line is behind schedule but is 98% completed. Revenue service is now expected in November 2022.
The Metro Crenshaw/LAX Line project is an 8.5-mile light rail (LRT) route, starting at the Expo/Crenshaw station on the E Line and connecting at a wye to the existing C Line just to the west of Aviation/LAX station. The initial segment includes eight stations; an infill station, Aviation/96th Street station, will be built later to accommodate a planned people mover system at LAX.
The northern half of the route follows Crenshaw Boulevard from Exposition Boulevard down to 67th Street. The southern half of the route utilizes the Harbor Subdivision Right-Of-Way (ROW) from Crenshaw Boulevard to the Green Line just west of Imperial/Aviation.
At its northern terminus, Metro has decided not to directly connect the Crenshaw Line track to the at-grade E Line track. Such a connection would have allowed the Crenshaw Line to interline with the E Line and terminate in Downtown Los Angeles. However, Metro argues that this is not operationally feasible (three lines would share tracks on Flower Street leading into Downtown, putting the tracks above their maximum capacity, leading to delays), and is therefore not worth the cost. Instead, its northern terminus will be an underground subway station at Expo/Crenshaw, built to enable a planned northern extension to the D Line and the Hollywood/Highland station on the B Line in Hollywood.
The project will include nine new Metro stations, including an infill station that will not open until several years after the rest of the line:
The question of how the new segment would be integrated into the Metro Rail system was the subject of some controversy in 2018 as completion of the project seemed looming. Early proposals had suggested that a new line would operate between Expo/Crenshaw station in the north and Aviation/Century station in the south or possibly extend to Redondo Beach station once the stations west of Aviation/LAX station could accommodate 3-car trains, with the stretch southwest of the wye continuing to be served by the C Line as well. An additional service would have connected Norwalk station to the new Aviation/Century station and planned LAX/Metro Transit Center, as well as the LAX Automated People Mover.
Los Angeles Railway Line 5 yellow streetcars served Crenshaw and Florence Boulevards until 1955 when the service was replaced with buses.
Extending the Green Line to LAX was an early goal of Los Angeles transit planners. Studies in 1984 and 1988 outlined a route from the junction near Aviation/Century and running to the northeast, similar to later plans for the second section of the Sepulveda Pass Transit Corridor.
The line was planned following the Los Angeles riots of 1992 as a way to better serve transit-dependent residents in the corridor while at the same time providing stimulus for positive economic growth in the South Los Angeles region. It was championed by State Senator Diane Watson and County Supervisor Yvonne Brathwaite Burke, both representing portions of the corridor.
In 1993 and 1994, a Major Investment Study (MIS) was initiated. At that time, the project was referred to as the Crenshaw–Prairie Corridor. A route refinement study followed in 1999–2000 to improve the shelf life and to narrow down the number of alternatives. An architectural design and planning visioning was performed by the University of Southern California school of Architecture in 1996. A new Major Investment Study (MIS) was completed in 2003. From 2007 through 2009, Metro conducted a draft environmental review of the line, taking public input and analyzing the environmental impacts and benefits of various alternatives. In December 2009, the Metro Board approved the Draft Environmental Impact Report and chose a "Locally Preferred Alternative".
This alternative, which included the preferred mode and route, became the subject of a final environmental study, resulting in a Final Environmental Impact Report. This final study was completed in May 2011. Local community leaders, neighborhood councils, Los Angeles County Supervisors Yvonne Burke and Mark Ridley-Thomas, as well as U.S. Representative Diane Watson continued to express enthusiastic support for the proposed light rail line. In a letter to Metro dated November 5, 2007, Watson wrote:
Having advocated strenuously for a light rail 'spur line' to carry passengers from the Wilshire Corridor down the Crenshaw Corridor and, ultimately, to LAX for 25 years now, I am delighted to offer continued encouragement, advocacy and feedback for a Metro study (to)…avoid aggravating (the) Leimert Park traffic bottleneck, Coliseum to Vernon;…Wilshire/La Brea station connection to Westside Corridor line, avoiding hydrogen sulfide;…fully consider (the) below-grade option. (Comment ID 116-125 in the cited link)
The route was designated as the K Line by November 2019.
In April 2020, Metro announced that the completion date for the project would be pushed to no earlier than May 2021 due to construction issues. The support structures for bridges and tunnels had concrete plinths that were incorrectly installed, requiring extensive repairs to sections where tracks had already been installed.
The Draft Environmental Impact Report (DEIR) describes several alternatives, as well as "Design Options" (optional features with additional cost). Many other alignments were considered previously, but eliminated due to lack of feasibility or benefit.
The following table summarizes key characteristics of each alternative:
The route had several segments under consideration for grade-separations. The LRT Baseline (DEIR) included a minimal set of grade separations: the design options specified additional grade separations. The locally preferred alternative (LPA) adopted by the Metro Board included the LRT Baseline plus some additional grade separations (e.g. Design Options 1, 2 and 4). Other grade separations were also still under consideration. All grade separations are subject to the Metro Grade Crossing Policy.
The following table describes the Crenshaw Corridor's route, divided into segments with potential grade-separations:
Metro staff studied and ranked 16 potential sites for the required maintenance facility. Through several rounds of screening, all but five were eliminated.
In March 2011, a Supplemental DEIS/R was released to the public, specifically related to the maintenance facility. This study was completed due to changes to capacity requirements of the Crenshaw Line. Three of the screened sites were carried forward into this study, and one new site was added. The four site options studied in the Supplemental DEIS/R (from north to south) are:
Following the public comment period in April 2011, staff recommended adoption of the Arbor Vitae/Bellanca site, since it had no public objections and all environmental impacts could be mitigated.
In 2010, Supervisor Mark Ridley-Thomas requested study of a tunnel through Park Mesa Heights on Crenshaw Boulevard between 48th and 59th Streets. Metro staff studied the option and recommended against it. Staff concluded the option offers minimal benefit but high cost. The additional cost for the tunnel would be $219 million, or $167 million with Slauson station removed. Instead that section of the line will be at-grade level.
In May 2011, Supervisor Ridley-Thomas asked the Metro Board to vote on a motion requiring construction of both the tunnel and the subway station in Leimert Park Plaza (Crenshaw/Vernon). The Board voted to include an underground station at Leimert Park and approved the station only under the condition that the entire project can be completed within its original budget.
In May 2013, the Metro Board voted 10-1 to officially include an underground station at Leimert Park (Crenshaw/Vernon, at Crenshaw Blvd and 43rd Place), and another at-grade station at Hindry Ave (Florence/Hindry), in the Crenshaw/LAX Line project.
In 2014, Metro approved the planning and scoping of an infill station at 96th and Aviation, which would connect to the proposed LAX Train automated people mover system to the airport terminals.</ref> The station would be less than half a mile north of the under construction Aviation/Century station, and would serve as Metro Rail's main gateway to the airport itself, while the Aviation/Century station would serve destinations along the busy Century Boulevard corridor. The proposed station would be served by Green Line trains as well as trains along the new Crenshaw/LAX Line.
In December 2009, the Metro Board selected a Locally Preferred Alternative (LPA), and in 2010 Metro conducted the Final Environmental Study for this alternative. This alternative included the LRT Baseline alignment, plus Design Options 1, 2 and 4. At this time, Metro also authorized further study of the remaining design options.
In selecting this alternative, Metro staff eliminated the BRT (bus rapid transit) alternative, stating that it was too slow to provide much benefit, and that it generally lacked public support.
Metro staff also concluded that the northernmost portion of the Crenshaw Corridor between Exposition and Wilshire was too expensive to include in the project if implemented as light-rail. Thus, study and implementation of that segment was deferred, to be considered separately in the future as a northern extension ("Phase 2") of the Crenshaw Line (see section below).
Metro estimated the light-rail line will initially have a daily ridership between 13,000 and 16,000, would cost $1.3 billion - $1.8 billion (in 2008 dollars), would take five years to complete construction, and would generate 7,800 construction jobs over this period.
