The Federal Bridge Gross Weight Formula, also known as Bridge Formula B or the Federal Bridge Formula, is a mathematical formula in use in the United States by truck drivers and Department of Transportation (DOT) officials to determine the appropriate maximum gross weight for a commercial motor vehicle (CMV) based on axle number and spacing ...

A demonstration of truck weight distribution, illustrating a practical application of the Federal Bridge Gross Weight Formula. Date: 2 April 2008: Source:
Trailing 11 to 13 feet (3.35 to 3.96 m) behind the rear tandem, the trailing axle stretches the outer "bridge" measurement—the distance between the first and last axles—to the maximum overall length allowed. This increases the gross weight allowed under the federal bridge formula, which sets standards for truck size and weight.
The Federal-Aid Highway Amendments of 1974 was signed into law by President of the United States Gerald Ford on January 4, 1975. [1] Among other changes, the law permanently implemented a national 55-mph speed limit (which had already been a temporary limit) for the Interstate Highway System .
The Federal-Aid Highway Amendments of 1974 established a federal maximum gross vehicle weight of 80,000 pounds (36,000 kg), and introduced a sliding scale of truck weight-to-length ratios based on the bridge formula, but did not establish a federal minimum weight limit.
The axle load of a wheeled vehicle is the total weight bearing on the roadway for all wheels connected to a given axle.Axle load is an important design consideration in the engineering of roadways and railways, as both are designed to tolerate a maximum weight-per-axle (axle load); exceeding the maximum rated axle load will cause damage to the roadway or railway tracks.
