WebBridge Weight Formula The maximum weight on any group of consecutive axles is limited by the Bridge Weight Formula: W = 500 [ (LxN)÷ (N-1)+12N+36] Where: W = Maximum Weight, rounded to the nearest 500 pounds L = Distance in feet between the extreme axles of a group (this distance is called the “bridge” distance) N = Number of axles in a group There is one exception to the formula: two consecutive sets of tandem axles may carry 34,000 pounds (15,000 kg) each if the overall distance between the first and last axles of these tandems is 36 feet (11 m) or more. For example, a five-axle truck may carry 34,000 pounds both on the tractor tandem axles (2 and 3) and the trailer tandem axles (4 and 5), provided axles 2 and 5 are spaced at least 36 feet (11 m) apart.

2024 Federal Bridge Formula Weights Explanation
WebW = 500 ( (LN/ (N - 1)) + 12N + 36), Where: W = gross weight, L = wheelbase in feet, and N = number of axles, except two consecutive sets of tandem axles may carry a gross load of 34,000 pounds each if the overall distance between the first and last axle of the consecutive sets of tandem axles is 36 feet or more. WebThe formula is as follows: W = the maximum weight in pounds that can be carried on a group of two or more axles to the nearest 500 pounds (230 kg). L = spacing in feet … WebJul 9, 2011 · Thus, a bridge weight formula is also applied to commercial vehicles in determining their compliance with Federal weight limits.
