The Chesapeake Bay Bridge-Tunnel (CBBT) is a four-lane, 17.6-mile-long (28.3 km) bridge-tunnel structure that crosses the Chesapeake Bay in the Mid-Atlantic Region. The official name is the Lucius J. Kellam Jr. Bridge–Tunnel to commemorate one of the civic leaders who pushed for the structure’s development. Due to their similar names, this bridge is often confused with the Chesapeake Bay Bridge, which is located further up the estuary. Curious to learn more about this incredible feat of engineering?
