Bridgedeck — PRISM Climate Features at Bridge Locations (2000–2023)

Part of the bridgedeck dataset collection for US bridge deck deterioration research.

Overview

Annual climate features sampled at every CONUS bridge location from PRISM 4 km gridded climate rasters, 2000–2023. Covers temperature, precipitation, freeze-thaw cycles, and seasonal extremes — the key environmental drivers of bridge deck deterioration via thermal expansion, moisture infiltration, and freeze-thaw spalling.

Source

Source: PRISM Climate Group, Oregon State University

Products used:

• Annual tmean (mean temperature) and ppt (precipitation), 2000–2023
• Monthly tmin and tmax, 2000–2023 (for freeze-thaw and seasonal features)

Resolution: 4 km gridded rasters (AN81m product). Bridge values obtained via nearest-neighbour sampling (rasterio).

Schema

One row per (bridge_id, year). Primary key: (bridge_id, year).

Column	Type	Description
bridge_id	str	{state_fips}_{county_fips}_{structure_number} — joins to NBI
year	int	Year (2000–2023)
tmean_annual	float	Mean annual temperature at bridge location (°C)
ppt_annual	float	Total annual precipitation (mm)
freeze_thaw_months	float	Months/year where mean Tmin < 0°C AND Tmax > 0°C (freeze-thaw proxy)
tmin_winter	float	Mean Dec–Jan–Feb minimum temperature (°C) — cold exposure
tmax_summer	float	Mean Jun–Jul–Aug maximum temperature (°C) — heat exposure
tmean_annual_5yr_avg	float	5-year rolling mean of tmean_annual
ppt_annual_5yr_avg	float	5-year rolling mean of ppt_annual
freeze_thaw_months_5yr_avg	float	5-year rolling mean of freeze_thaw_months
tmin_winter_5yr_avg	float	5-year rolling mean of tmin_winter
tmax_summer_5yr_avg	float	5-year rolling mean of tmax_summer

Coverage

• CONUS only — AK, HI, and PR are not covered by PRISM and have NaN values.
• ~0.4% null for single-year features (bridges near PRISM grid boundary).
• ~13.2% null for 5-year rolling averages (years 2000–2001 have insufficient history; min_periods=3 applied).
