Distinguished as an "Outstanding Civil Engineering Achievement" by the American Society of Civil Engineers in 1965, the Chesapeake Bay Bridge-Tunnel is nothing short of a modern engineering wonder. Dipping over and under open waters with a complex chain of artificial islands, tunnels, and bridges, the Chesapeake Bay Bridge provides a direct link between Southeastern Virginia and the Delmarva (Delaware, Maryland, and Virginia) Peninsula. The bridge-tunnel complex is 17.6 miles long from shore to shore, and it cuts 95 miles from the journey between Virginia Beach and points north of Wilmington, Delaware.
The majority of the bridge-tunnel complex is above the water, supported by more than 5,000 piers. But due to the importance of shipping in the bay, the crossing was sunk deep beneath the bay in two mile-long tunnels, to allow the passage of ships. Four artificial islands, each with approximately ten acres of surface, provide the portals by which the road enters the tunnels. Itís quite an eerie experience to be driving along and see the road youíre on disappear into the bay. Millions of cars have crossed the Chesapeake Bay Bridge-Tunnel since it opened in 1965. Itís possible that many just crossed it for the thrill of it!Here's how this tunnel stacks up against some of the longest tunnels in the world.
