Williamsburg VA to Virginia Beach

That area is the largest deep water port on the east coast. The tunnels are well lit and the underwater part is short. OTOH, the US 17 bridge is long and high enough for those same ships to go under it. There's a lot more of those ships above the water line than below it. The Jamestown-Scotland ferry is fun, but the lines are long and the trip is SLOW.
Besides, you get to tell your buddies at home that you were run over by an aircraft carrier. :)
