Chesapeake Bay Bridge-Tunnel
Chesapeake Bay Bridge-Tunnel, officially the Lucius J. Kellam, Jr. Bridge-Tunnel, 17.6 mi (28.2 km) long, across the mouth of Chesapeake Bay, E Va., connecting Cape Charles with Norfolk, Va. Opened in 1964, the original roadway consisted of a chain of low trestle bridges, two high bridges, and two tunnels (each 1 mi/1.6 km long) under the shipping channels. The tunnels are anchored on four artificial islands. A set of parallel bridges, but not tunnels, opened in 1999.
