When you’re ready to add a timber vehicular bridge to your commercial and residential developments, parks, property, or golf course, you’ll usually need to get permission from at least one governmental authority. For example, you may need permission for changing an existing grade, moving earth for a foundation, locating a bridge within a flood plain, and closing any stream or body of water.
The agencies that grant permits include Water Control Districts, Departments of Natural Resources, Departments of Environmental Regulation, and other similar regulatory agencies. If needed, we can provide preliminary drawings for review by the appropriate authorities.
Bridge Builders ™ can design a timber bridge to meet your local codes and regulations. We are very familiar with design restrictions and requirements nationwide. Bridge Builders ™ has placed timber vehicular bridges and boardwalks coast to coast throughout the United States and Guam.
You will need to consider many factors as you decide where to build your timber vehicular bridge. First, you’ll need to consider the high water elevation at your proposed timber bridge site. Usually you will want to locate the timber bridge so that there is a clearance or free board between the bottom of the timber bridge and the high water elevation or 100-year flood level. These criteria may determine the length of the timber bridge in some locations.
The grades of the approaches and banks of the stream or pond also can affect timber bridge length. You’ll want to have a relatively flat approach to the bridge if this can be accomplished without major grading.
The best tool in determining your bridge size is a tape measure. Measure your proposed location keeping these points in mind and try to minimize the span.
The most common design codes and specifications used for timber vehicular bridge design are:

Height – This is the distance from the deepest location of the pond, ravine, creek, etc. to the top of the deck of the timber bridge. You can figure out the height by knowing:
Length - The drawing represents the fact that you will typically measure at least 5 feet, and perhaps 10 feet or more, past the top of the bank on each side of your crossing. Keep in mind when determining this figure any environmental constraints and set backs that may require more than 5 – 10 feet from the top of the bank.

Director of Construction
Nature Walk at Seagrove, Santa Rosa Beach, Florida
Bridge Builders did a simply superb job in building the timber bridge at our master planned community in Seagrove. At 780 feet, we now have the longest HS-25 vehicular timber bridge in the country. I don’t know if any other bridge construction company could have matched the level of craftsmanship it required. Bridge Builders’ attention to details and construction expertise at the job site was evident from beginning to end. Your crew’s ability to get things done was exceptional. They defined the word “professionalism.” I have recommended Bridge Builders to many other companies and will continue to do so whole-heartedly in the future.
