Missouri material haulers could exceed weight limits outside interstate highways

Haulers on covered routes would be allowed to exceed the vehicle weight limits in section 304.180 by up to 10%. The allowance would cover construction materials hauled from production sites to projects where they will be used, or raw ingredients hauled from their origin to sites that make construction materials. It would exclude Missouri interstate highways. Vehicles would need proper maintenance and equipment to carry the extra weight safely without exceeding the manufacturer’s maximum loaded weight. Vehicles using the allowance could not cross a bridge or other structure with a posted weight limit below their total loaded weight. Vehicles using the allowance could travel no faster than 30 miles per hour on any bridge or other structure with a posted weight limit.
