The Chesapeake Bay Bridge-Tunnel is a 23-mile, open-water drive across the influx of Chesapeake Bay. This highway system traverses a series of shorter spans in which most of the spans are of similar length, raised roads or path across wet ground or through water, bridges, artificial islands, and tunnels to link the southern tip of the Delmarva Peninsula with the Norfolk-Virginia Beach area. The at-sea a particular place or position also makes this the best place in Virginia to watch sea birds. The road over the water is broken up by two underwater passages. A stop at the restaurant and fishing vertical structure which supports the ends of a multi-span superstructure at a location between abutments 4 miles out at sea on one of the manmade pieces of land completely surrounded by water gives you the possibility to walk out over the water to look at birds, ocean-going ships, and views of the distant land along the edge of a large area of water.
