Driving Rules for RVs Through the Chesapeake Bay Bridge-Tunnel

Before you embark on this breathtaking journey, there are some essential driving rules and tips you should be aware of:

Height and Width Restrictions

The Chesapeake Bay Bridge Tunnel (CBBT) has height and width restrictions on RVs for safety reasons. The tunnels on the CBBT are only so tall and wide, so RVs must be under 13 feet 6 inches tall and 10 feet 6 inches wide in order to fit through.

If an RV is too tall or wide, it could get stuck in the tunnels. This would cause a major traffic jam, as other vehicles would not be able to pass. It could also create a safety hazard, as emergency vehicles may not be able to reach the scene of an accident if an RV is blocking the road.

The CBBT has height and width sensors at the entrances to the tunnels. If an RV is too tall or wide, the sensors will trigger an alarm and the RV will not be allowed to enter the tunnel.

If you are planning to drive your RV through the CBBT, be sure to check the height and width of your RV before you go. You can find this information in your RV’s owner’s manual. If your RV is too tall or wide, you will need to find an alternate route.

Propane Tank Restrictions

Propane is a flammable gas, so it is important to turn off and secure all propane tanks before entering a tunnel. This is to prevent a fire hazard in the event of an accident.

If an accident occurs in a tunnel, there is a risk of sparks or flames. If there is propane in the air, it could ignite and cause a fire. This fire could spread quickly in a tunnel, as the tunnels are enclosed spaces and the fire would have plenty of fuel to feed on.

A fire in a tunnel could be very dangerous, as it could trap people and vehicles inside. It could also damage the tunnel itself, making it difficult or impossible to use for a long period of time.

To prevent a fire hazard, it is important to turn off and secure all propane tanks before entering a tunnel. This means turning off the valve on the tank and closing the lid tightly. The tank should also be secured to the RV so that it cannot move around in the event of an accident.

High Wind Restrictions

The CBBT can be windy, especially during the spring and fall months. RVs are more susceptible to being blown around by high winds, so they may be restricted from crossing the CBBT during periods of high winds. This is to prevent RVs from being blown off the road or into oncoming traffic.

There are three levels of Wind restrictions on the CBBT. You can take your RV and drive on until the wind speed reaches more than 35 miles per hour. When the wind speed reaches 35 miles per hour, your speed needs to be reduced to 45 mph and when the wind speed reaches 40 miles per hour, you won’t be able to take your RV through the CBBT.

These restrictions are in place to protect the safety of all drivers who use the CBBT. If you are planning to drive your RV through the CBBT, be sure to check the CBBT website for current conditions and restrictions.
