The Nationwide Transportation Security Board is warning that 68 bridges in 19 states needs to be inspected for his or her danger of collapse if a vessel have been to collide with them. The suggestions come within the wake of the investigation into the collapse of the Francis Scott Key Bridge final yr and are based mostly on the truth that the bridges have been constructed earlier than 1991, when new pointers have been put into place. These pointers got here after the lethal 1980 collapse of the Sunshine Skyway Bridge throughout Florida’s Tampa Bay, which occurred when a freighter hit it in stormy climate. The bridge that changed that one is on the NTSB’s new listing. Others embrace San Francisco’s Golden Gate Bridge and each the Brooklyn Bridge and George Washington Bridge in New York Metropolis. The NTSB notes the bridges aren’t essentially in peril, however fairly that their danger is unknown.
