Chesapeake Bay Bridge–Tunnel
The bridge that converts into tunnel and goes directly into the water. This wonder of engineering connects the Delmarva Peninsula with Virginia Beach and the Norfolk (Hampton) Roads metropolitan area in U.S state of Virginia. The bridge–tunnel originally combined 19 kilometers of trestle, two 1.6 kilometers-long tunnels, four artificial islands, four high-level bridges, approximately 3.2 kilometers of causeway, and 8.9 kilometers of approach roads.
