Bridge Load Posting Program
You may have noticed that we’ve started placing new signs at some of the bridges around the state. Those new load posting signs are part of the Montana Bridge Load Posting Program.
Bridge load posting is a matter of public safety and will help us safeguard vital transportation infrastructure. Based on recent safety-based bridge engineering evaluations, new vehicle types, and updated mandates from the Federal Highway Administration (FHWA), the new load postings will indicate the maximum amount of weight that can legally cross a bridge for different vehicle types.
Not all bridges were designed to carry today’s standard legal loads, and some bridges have deteriorated over time. A posted bridge is safe to use, but the weight of certain vehicles must be limited accordingly. MDT needs your help to prevent overload and damage, maintain the integrity of the bridge, and safeguard bridge longevity.
