The standard height of a bridge is 16 feet.

On Interstates, the clear height of bridges and structures shall not be less than 16 feet (4.9 meters) over the entire roadway width, including the useable width of shoulder.

In urban areas, the 16-foot (4.9-meter) clearance shall apply to at least a single routing.

In some areas a bridge height may only be 11 feet depending on the age of the bridge and location.

The bridge should have the height of the bridge shown on it before you reach the bridge.

Always know the height of your vehicle that is going to need to pass under the bridge.

If you're driving an RV or pulling a travel trailer you need to know the height of the trailer or RV including the rooftop air conditioner and have the height written down and placed on your dash so you'll always know.

But most bridges are at a height high enough to allow campers, RV's and Motor homes, Travel Trailers etc and semi trailers to pass under without a problem.

16 feet is the standard height and clearance of bridges.

However some bridges may only have 11 foot clearance if they are older bridges.
