Driving south on Route 13, the horizon basically swallows the road. You’re in the middle of the Atlantic Ocean—sorta—and then suddenly, the pavement just dips into the water. It’s a bit unnerving the first time. Honestly, most people think they’re just crossing a long bridge when they head toward Virginia Beach, but the Chesapeake Bay Bridge Tunnel Virginia (CBBT) is a whole different beast. It’s an engineering fever dream that somehow works.
It isn't just one thing. It's a 17.6-mile jigsaw puzzle of trestles, man-made islands, and tunnels that dive deep under shipping channels.
People get this confused with the "Bay Bridge" near Annapolis all the time. Don't be that person. That one is a suspension bridge in Maryland. This one? This is the one where you drive under the aircraft carriers.
The "Seven Wonders" Label Isn't Just Marketing
Back in 1964, when the CBBT first opened, the American Society of Civil Engineers called it one of the Seven Engineering Wonders of the Modern World. They weren't kidding. Imagine trying to build a 23-mile fix-link (counting the approach roads) in the early 60s without modern GPS or advanced computer modeling.
The crews had to deal with Nor'easters and literal hurricanes. One massive machine, nicknamed "The Two-Headed Monster," was built specifically to place the concrete "bents" that hold up the road. Another one called "Big D" drove the piles into the sea floor. During the Ash Wednesday Storm of 1962, the "Big D" was actually wrecked by the waves. It was chaos.

Why Does the Road Keep Disappearing?
The most common question from first-timers is: "Why didn't they just build a bridge the whole way?"
It comes down to the Navy. The Chesapeake Bay is home to the world’s largest naval base in Norfolk. If a bridge over the main shipping channels ever collapsed—whether by accident or an act of war—the entire Atlantic Fleet would be trapped in the bay. Tunnels solve that. By sinking the road into the mud, the Navy’s massive ships can pass overhead without a care in the world.
The Tunnel Layout
- Thimble Shoal Tunnel: This is the southern one, closest to Virginia Beach.
- Chesapeake Channel Tunnel: The northern one, closer to the Eastern Shore.
- The Islands: There are four man-made islands (about 10 acres each) that act as the transition points where the bridge becomes a tunnel.
The water here is anywhere from 25 to 100 feet deep. When you’re inside those tunnels, you’re basically driving through a tube that was lowered into a trench in the ocean floor and covered with rocks. It’s wild to think about while you're listening to the radio.

The "Chessie" Expansion: What’s Happening Now?
If you've driven the bridge recently, you've seen the cranes. They are currently building a parallel tunnel at Thimble Shoal.
They’re using a massive Tunnel Boring Machine (TBM) named Chessie. This thing is a beast—308 feet long with a 43.5-foot diameter cutterhead. Unlike the original tunnels, which were "dropped" into the water in sections, Chessie is chewing through the earth underneath the bay floor.
The project has hit some snags. Originally, it was supposed to be done by now, but geological surprises (like massive boulders) and technical delays have pushed the expected completion to roughly 2028. Once it’s done, the whole 20-mile stretch will finally be a full four-lane highway, ending those annoying two-lane bottlenecks in the tunnels.
Practical Stuff: Tolls and Survival
Let’s talk money because it isn't cheap. As of 2024/2025, a one-way trip for a standard car starts around $16 off-peak and jumps to $18 during peak hours (Friday through Sunday in the summer).

Pro Tip: If you return within 24 hours and use an E-ZPass, the return trip is only $6 (off-peak) or $2 (peak). It’s a massive discount that most tourists miss because they don't have a transponder or they stay for a week.
Wind Restrictions: A Real Concern
The CBBT doesn't mess around with weather. Because you’re so exposed, wind is the enemy.
- Level 1: Winds at 40 mph. No empty trailers or campers.
- Level 6: Hurricane-force winds. The whole thing shuts down.
If you have "gephyrophobia" (fear of bridges), the CBBT actually offers a drive-over service. You call ahead, and an employee will drive your car across while you sit in the passenger seat with your eyes closed. Seriously. They do this for dozens of people every month.
What Most People Miss
Don't just zoom across. Most people treat it as a shortcut to bypass I-95, but it’s a destination.
Stop at the scenic overlooks. The northern end near Fisherman Island is a prime spot for birdwatching—migratory birds use the bridge as a rest stop. There used to be a famous restaurant and fishing pier on the first island, but those are currently closed due to the "Chessie" construction. Keep an eye on the official CBBT updates, as they plan to bring back some of these amenities once the new tunnel is finished.
Actionable Insights for Your Trip
- Check the Wind: Before you leave, check the CBBT Twitter (X) feed or their official site. If there’s a Nor'easter, you might get turned around if you're in a high-profile vehicle.
- Get an E-ZPass: You’ll save hours of waiting in line during summer weekends, and it’s the only way to get the 24-hour round-trip discount.
- Fuel Up: There are no gas stations on the 17-mile span. If you run out of gas in the tunnel, it’s an expensive tow and a lot of angry commuters.
- Speed Limits: They are strictly enforced by the CBBT Police. The limit drops significantly when you enter the tunnels (usually 45 mph). Don't test them.
The Chesapeake Bay Bridge Tunnel Virginia is more than just a road; it's a testament to what we can build when we decide to conquer the ocean. Whether you're there for the engineering or just trying to get to the Outer Banks faster, it’s a drive you won't forget.
