This is a photo of the huge Chesapeake Bay Bridge. I didn't take this one. Thanks to the Va. Chesapeake Bay website you can get a clue about how HUGE this bridge is.
Crossing this bridge is a really scary thing. You go over the bay for awhile, looking down at the small ships and boats.
Then you get to go under the bay so the big ships, like tankers and Navy ships can go up the bay. That means you're going under the water.
You enter through a long tunnel
It's a long tunnel, lit well with spots to pull off in case of an emergency. This is the biggest bridge I've been on.
