The Bridge Formula Weights Calculator provides a convenient way to determine the maximum allowable weight that any set of axles on a motor vehicle may carry on the Interstate highway system.

Congress enacted the Bridge Formula in 1975 to limit the weight-to-length ratio of a vehicle crossing a bridge. This is accomplished either by spreading weight over additional axles or by increasing the distance between axles.
