How do I change the allowable weight limit on a bridge?


The first step is to determine the allowable load on the bridge. This must be done by a licensed professional engineer. If the engineering review determines the weight limit should be changed, the next steps depend upon who owns and maintains the bridge.

In all cases, signage on the approach to the bridge notifying the public of the change is also required. It is recommended that the posting also be publicized in the local paper and media.

In the case of an emergency, the Highway Superintendent or responsible official for a City or Village may close a road or a bridge, but must notify the municipal clerk and the emergency management/sheriff’s offices of the changes.
