Bridge and tunnel strikes damage infrastructure, damage vehicles and cargo, create traffic delays, disrupt access to communities, and kill and injure people. There has been an increase in bridge and tunnel strikes in the U.S., with nearly 15,000 bridge strikes annually, costing millions of dollars in repairs and posing serious safety risks. The pressing need for a comprehensive solution is evident.
This week, TRB's National Cooperative Highway Research Program has released two new reports designed to help. NCHRP Research Report 1132: Bridge and Tunnel Strikes: A Guide for Prevention and Mitigation and NCHRP Web-Only Document 411: Prevention and Mitigation of Bridge and Tunnel Strikes present state-of-the-art information to assist state departments of transportation in the prevention and mitigation of bridge and tunnel strikes by overheight motor vehicles.
