Bridge Weight-Limit Posting Practice

TRB's National Cooperative Highway Research Program (NCHRP) has released Synthesis 108: Bridge Weight-Limit Posting Practice. Highway agencies use posted weight-limits to allow continued, limited use of bridges for which the maximum legal load produces stresses in excess of specified levels. This report of the Transportation Research Board contains background information on load-limit posting practices and includes a review of administrative and engineering factors considered in current practice.
