That blue-white colour scheme for street furniture is a very common pattern in Nanning (Guangxi), but of course exists in some other southern cities too.\n\n2. The striking clue – a bright-white elliptical “arch / ring” visible in the distance, centred on the roadway. \n • It is not a Ferris wheel (no spokes). \n • It looks almost exactly like the single-arch “Nanning Yonghe Bridge” (邕河大桥, also called Yongjiang Bridge) across the Yong River. When viewed along Binhu Road or Fengling South Rd the arch makes a pure white oval shape on the horizon, identical to the picture.\n\n3. Road sign \n • Under the traffic light, the blue street-name plate is short (two Chinese characters) plus “Lu” or “Road” in pinyin. From the frame, the first character seems like “仁” and the second could be “和”. Nanning indeed has a 仁和路 (Renhe Road) in the Qingxiu district, running roughly east-west and leading towards the Yonghe Bridge. The geometry of the Google/Baidu map street-view for that stretch matches the perspective: tall residential towers on the south side, trees on the median, and the bridge’s arch visible dead ahead.\n\nBecause both the distinctive white arch and the blue-bottom lamppost style are signature visuals of Nanning, and there is a Renhe Road lining up to the bridge, the city is almost certainly Nanning (南宁市), capital of Guangxi.\n\nNo other large Chinese city has that exact single pure-white oval arch bridge in an urban core setting.\n\nHence: City = Nanning.

Background analysis \n• The image is a 1950-s snapshot on a broad, flat, sandy beach. \n• Behind the people is a long, straight concrete sea-wall with a uniform metal railing on its crest; the wall slopes down toward the sand and is painted a very light (almost white) colour. \n• There is no high cliff – directly behind the rail you can already see low houses and other seafront buildings. \n• A ramp / set of steps descends from the crest to the beach. \n• No wooden groynes are evident.\n\n2. What coast matches that construction style in the 1950s? \n• South-east England had a major post-war concrete sea-wall project protecting Romney Marsh, running from Hythe through Dymchurch to St Mary’s Bay. \n• That wall looks exactly like the one in the picture: shallow white-painted concrete slope, path on top, tubular/rod iron rail, houses immediately landward, and occasional concrete ramps.\n\n3. Other North-European coasts (Belgium, Netherlands, Germany) usually have dunes or high promenades rather than a shallow white concrete revetment; Germany and the Netherlands would also show wicker “Strandkorb” baskets rather than simple deck-chairs.\n\n4. Pin-pointing along the Romney Marsh wall \n• Dymchurch is the best-known holiday beach along that stretch in the 1950s, with deck-chair hire, fairground, etc. \n• The village front faces a long straight section of the wall; houses and amusements sit only a few metres behind the rail – matching the visible roofs in the photo.\n\n5.

The picture shows a straight, multi-lane north–south street with an overhead street-name sign that clearly reads “8TH ST”. \n • That means the traffic lights we see belong to the junction of Main Street and E/W 8th Street. \n • In Rochester, the principal north–south artery through downtown is Main Street (also signed as IN-25). \n3. Therefore the camera is sitting on Main Street at the 8th Street intersection, looking north (the courthouse square is a block ahead at 9th Street – consistent with the low-rise historic façades we can see). \n4.

Sign clues \n• The text is clearly aimed at employees who must “cross the plaza”, “approach vehicles” and “work in live traffic” – classic wording found on Port Authority of NY & NJ safety boards at their toll plazas. \n• New York-area toll facilities with plazas that still require employees to walk between booths are the four major tunnels: Lincoln, Holland, Queens-Midtown and Hugh L. Carey (Brooklyn-Battery).\n\n2. What we can see \n• In the left background the night skyline shows One World Trade Center with its spire lit. \n• The camera is therefore looking roughly east-north-east toward Lower Manhattan. \n• No river is visible, only a broad, multi-lane expanse of roadway immediately in front – a toll plaza apron rather than a waterfront promenade.\n\n3. Candidate plazas vs. skyline direction \n• Lincoln Tunnel NJ plaza looks toward Midtown, not Lower Manhattan. \n• Queens-Midtown Tunnel (Queens side) looks toward Midtown as well. \n• Hugh L. Carey Tunnel Brooklyn plaza faces south-west toward the harbor and Statue of Liberty, not straight to One WTC. \n• Holland Tunnel NJ (Boyle Plaza) sits directly west of Lower Manhattan; from it you look straight across the Hudson at One WTC – exactly the view in the photo.\n\n4. Extra confirmation \n• Boyle Plaza is the only Port Authority site that is literally called a “plaza” in daily usage. \n• The vertical purple/blue illuminated mast in the picture matches traffic-control beacons mounted on the islands of the Holland Tunnel NJ plaza. \n\n5.
