Drove south out of DC and found the longest bridge/tunnel in the US: the Chesapeake Bay Bridge-Tunnel (15 miles long). Felt like I was driving out into the Atlantic.
First, a high rise followed by miles of low bridge. 
Then, out in the middle of the ocean-size bay, suddenly the road dives below the water level into a mile or two of submarine tunnel.
Then more low bridge looking like you’re heading for Portugal. 
This repeats a couple times (more tunnels). Of course You finally come out in Virginia Beach and Norfolk. Quite the ride.
