Driving an RV Across the Chesapeake Bay Bridge-Tunnel

After an eventful time in Virginia Beach, Virginia, we wanted to venture to Ocean City, Maryland, to visit some friends we had made on our 2022 transatlantic cruise. Crossing the Chesapeake Bay Bridge-Tunnel offered the quickest, most direct route, saving 95 miles and about three hours of travel time through the congested Washington, D.C., area. 

Considered one of the seven engineering wonders of the modern world, the Chesapeake Bay Bridge-Tunnel is a 17.6-mile crossing of the Chesapeake Bay. Since opening in 1964, it’s taken more than 140 million vehicles from Virginia Beach to the state’s Delmarva Peninsula, or vice versa, traversing both over and under the water.

The bridge-tunnel includes not one, but two tunnels, each about a mile long. Crossing the bridge-tunnel takes only about a half hour but can be nerve-racking in an RV if you’re unprepared for it. 

To Cross or Not to Cross?

As the time approached for us to travel to Ocean City, Bob put his excellent research skills to use to explore our options to get there. The bridge-tunnel’s direct route and time savings made us give it serious consideration. Had other RVs made it through? Did semi-trucks use the route? How tight were the travel lanes?

We had read that the max vehicle height for the tunnels is 13 feet, 6 inches, the size of semis. Our rig is 3 inches shorter, so we took some comfort in that, knowing we had a little more clearance than trucks did. 

Because of the potential stress of driving an RV across the bridge-tunnel, Bob had decided we’d forgo it and take the long, inland route instead. But advice from a friend made him reconsider. Jim had traveled the bridge-tunnel numerous times and had seen semis and RVs make it through with no issues. The only potential risk was weather. If conditions are too windy, the Chesapeake Bay Bridge and Tunnel Commission closes the bridge-tunnel until conditions improve.

We decided to keep our trip short and take the direct route across the bridge-tunnel.

Travel Day

The weather looked good on our day of departure. We waited to leave our campsite at First Landing State Park until about 9 a.m. to let traffic die down. Navigating to the bridge-tunnel proved easy enough. We made it to the toll plaza with no problems. 

Because we have E-ZPass, a transponder in Gulliver that electronically pays tolls we encounter, we didn’t have to exchange any funds. The toll worker asked if our propane was off. We assured her it was, and we were on our way, starting across the bridge.

A semi-truck passed us, relaxing any remaining frayed nerves. Prior to this experience, we had thought the dimensions listed before tunnels and overpasses — 13’ 6” max height, in this case —  were the measured distance from road to overpass/tunnel bottom. We learned those signs actually mean the listed dimensions are the maximum height for a vehicle to safely pass without hitting the bridge/tunnel.

As we approached the first of the two tunnels, Thimble Shoal Channel Tunnel, and two-way traffic, Bob concentrated on keeping Gulliver and Tagalong in the middle of our lane. Clearance under the tunnel was fine. We had no problems, although we still got excited when we could see the light at the end of the tunnel.

We emerged onto another bridge that led us to the second tunnel, the Chesapeake Channel Tunnel. As we approached that one, a semi-truck came out toward us, clearly demonstrating plenty of clearance. After that tunnel, we crossed another bridge before finally returning to land. 

Thankful for an uneventful experience, we pulled into the Eastern Shore of Virginia Welcome Center. There, we turned our propane back on to keep the food in our fridge and freezer cold as we journeyed to our destination in Ocean City.
