Tuesday 14th April 1964
The Chesapeake Bay Bridge-Tunnel connecting Kiptopeke and Chesapeake Beach, Virginia, US opened. The bridge-tunnel hybrid spans the entire mouth of the great Chesapeake Bay. It is the longest such structure in the world at 17.65 miles in length. The bridge-tunnel is essentially an artificial causeway raised on platforms. At the north end of the bay, a high extension bridge crosses a shipping lane. At the south end of the structure, two mile-long tunnels cross commercial shipping lanes.
