Description 

The Chesapeake Bay Bridge-Tunnel is one of longest bridges in the world. The crossing features a 75 foot high-level span over the North Channel, a 40 foot high-level span over Fishermans Inlet, a 5,237 ft. long tunnel beneath Chesapeake Channel, and a 5,552 ft. long tunnel beneath Thimble Shoal Channel.

Tunnels were chosen to cross Thimble Shoal and Chesapeake Channels at the request of the US Navy, who has a major Atlantic fleet based in Norfolk, about 7 miles from the bridge-tunnel. The navy feared that, in the event of war, an enemy might bomb and destroy high-level bridges over the shipping channels, and the wreckage would trap the naval fleet inside the Hampton Roads Harbor.

The original span opened in 1964, with the twin span trestles opening in 1999. Current plans are in place for new parallel tunnels to eliminate the dangerous merging two-way traffic in the current tunnels (funding permitting).
