Bridge and tunnel strikes inflict serious damage to vehicles, highway bridges, and tunnels; cause injuries and fatalities; and impose detours and costly delays on highway users. Attempts by state departments of transportation (DOTs) and other bridge and tunnel owners to prevent bridge and tunnel strikes include signing, lighting, height detection systems, and actuated warning devices.
NCHRP Research Report 1132: Bridge and Tunnel Strikes: A Guide for Prevention and Mitigation, from TRB's National Cooperative Highway Research Program, presents state-of-the-art information to assist state DOTs in the prevention and mitigation of bridge and tunnel strikes by overheight motor vehicles.
Supplemental to the report is NCHRP Web-Only Report 411: Prevention and Mitigation of Bridge and Tunnel Strikes. (2025).
