    • BETA - Hazard Exposure: National Highway System Bridges

    Metadata Updated: December 8, 2025

    The BETA - Hazard Exposure: National Highway System Bridges dataset was updated on October 16, 2025 from the Bureau of Transportation Statistics (BTS) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The BETA - Hazard Exposure: National Highway System Bridges dataset shows the exposure of bridges on the National Highway System to select natural hazards. The dataset combines hazard data from FEMA, USGS, NOAA, and USDA with information for relevant bridges in the National Bridge Inventory dataset from the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Hazard data include estimates of annualized frequency of Coastal Flooding, Cold Wave, Drought, Hail, Hurricane, Heat Wave, Ice Storm, Lightning, Strong Wind, Tornado, and Winter Weather from the FEMA National Risk Index. Landslide Index and Sinkhole Susceptibility derive from USGS models. USDA Burn Probability data underlie estimates of wildfire exposure. NOAA SLOSH models estimate storm surge inundation from hurricanes. The data set covers all 50 states of the United States, the District of Columbia, and Puerto Rico.
