Because I’ve seen several Facebooks posts recently about two bridges that can get confused with one another, I thought I’d nail it down especially for readers and travelers who aren’t familiar with the region. Because if you don’t know the difference…. Well, you’ll see.
The first is the Chesapeake Bay Bridge, referred to as the Bay Bridge. That’s what we called it when we lived in Maryland. When you “go down the ocean,” that’s Baltimore-speak for going to the beach on Maryland’s Eastern shore, you cross this 4-plus mile bridge over the Chesapeake Bay. This bridge is located just east of Annapolis. I’ve been over it many times.

The second bridge is the Chesapeake-Bay Bridge Tunnel in Virginia where the Chesapeake Bay meets the Atlantic Ocean. See what I mean about how it could be confusing which bridge is which. This road crosses the Bay and it also goes under the Bay. The entire length is 22 miles with the bridge and tunnel totaling just under 18 miles.

Depending where you’re coming from and where you’re going to, the bridge you take is important. In the map below, B is the Chesapeake Bay Bridge and A is the Chesapeake Bay Bridge-Tunnel.

There’s about 225 miles between the bridges taking a route on the western side of the Chesapeake Bay. Also, did you notice Washington, DC just west of the Chesapeake Bay Bridge? Just north of Alexandria. Maybe you’ve heard about all the traffic in that region? Especially around rush hours? If not, well, you don’t want to be in the middle of it.
So, if someone tells you to take the Chesapeake Bay Bridge or you hear something similar, listen very carefully. Or if you decide to put either bridge into your GPS, double-check you’ve selected the right one. That one word… TUNNEL ….. can make all the difference in how long and fun your trip will be.
