Chesapeake Bay Bridge


Chesapeake Bay Bridge–Tunnel (Virginia Bay Bridge)


The Chesapeake Bay Bridge–Tunnel (CBBT) is a 23-mile (37 km) fixed link crossing at the mouth of Chesapeake Bay in the U.S. state of Virginia. It connects the Delmarva Peninsula with Virginia Beach and the Hampton Roads metropolitan area.



The Virginia bridge–tunnel originally combined 12 miles (19 km) of trestle, two 1-mile-long (1.6 km) tunnels, four artificial islands, four high-level bridges, approximately 2 miles (3.2 km) of causeway, and 5.5 miles (8.9 km) of approach roads—crossing the Chesapeake Bay and preserving traffic on the Thimble Shoals and Chesapeake shipping channels. It replaced vehicle ferry services which operated from South Hampton Roads and from the Virginia Peninsula from the 1930s until completion of the bridge–tunnel in 1964. The system remains one of only ten bridge–tunnel systems in the world, three of which are located in Hampton Roads, Virginia.
