What It Means
When an engineering analysis determines a bridge cannot safely carry standard legal loads, the bridge is posted with weight restrictions. Posted bridges display signs indicating maximum allowable weights for single vehicles and combinations. Load posting is common for older bridges and those with deteriorated structural members. Heavy vehicles must use alternate routes, which can significantly impact commercial transportation and local economies.
