Chesapeake Bay Bridge-Tunnel

The Chesapeake Bay Bridge-Tunnel (CBBT) is a 23 mile long bridge and tunnel system that connects southeastern Virginia with Delmarva Peninsula in the United States. The bridge connects the following independent cities Virginia Beach, and Norfolk, Virginia to Cape Charles in Northampton County along the eastern shore of Virginia.




The Chesapeake Bay Bridge-Tunnel uses a combo of tunnels and bridges over two separated shipping channels using four artificial islands built in the bay as portals.

The bridge-tunnel was opened on April 15th, 1964, in August 1987 it was officially named the Lucius J. Kellam Jr. Bridge-Tunnel after one of the civic leaders who worked for its development. However, it still is best known as Chesapeake Bay Bridge-Tunnel.

The bridge part of the Chesapeake Bay Bridge-Tunnel as far as I can know is 15.6 Miles long which is why this bridge is placed at number at the worlds 9th longest bridge and 7th longest over water and 4th longest bridge in the USA and 8th longest that is used by autos.

The above water part of the bridge was upgraded in 1995-1999 from 2 lanes to a 4 lanes at a cost of $200 million.

After the bridge-tunnel opened in 1964, it was selected as One of the Seven Engineering Wonders of the Modern World by American Society of Civil Engineers, however it has been replaced on this list since with more recent engineering wonders.
