two weeks for repairs. On January 21, 1970, the USS Yancey (AKA-93), a United States Navy attack cargo ship carrying 250 people, was at anchor near the bridge–tunnel. During a gale with winds gusting in excess of , the Yancey dragged its anchors and hit the bridge stern first, knocking out a segment of trestle. There were no vehicles on the bridge at the time of the impact, and no one was injured. During the 42 days it took to replace the damaged span, the Navy offered a free shuttle service for commuters using helicopters and LCUs. In 1972, the bridge was again impacted by a barge that had broken loose, closing it for two weeks while the span was repaired. Other, less significant strikes have caused shorter closures while the affected structures are inspected—most recently, a four hour closure after a barge strike in June 2011. , there have been 16 incidents of vehicles running off the bridge and into the water. In 2017, a truck plowed through the barriers into the sea below; the driver was rescued but died en route to the hospital. In December 2020, a dairy truck crashed through the guardrail near mile 14. Witnesses saw the driver drifting in the water—estimated to be about —but were unable to rescue him. Despite an extensive search, he remained missing until April 2021, when his body washed up over south at Cape Hatteras National Seashore between Salvo and Avon. A second truck following the dairy truck encountered strong wind gusts just prior to the accident that blew it into the other lane.
