Several bridges in Chelan County are under weight restrictions. For these bridges, a vehicle's gross weight must not exceed the limits set by state laws. It is unlawful for the operator of any vehicle to drive upon these bridges when the gross load limit exceeds the weight in tons as set forth for these bridges.
In addition, new load-rating signs have been installed at some Chelan County bridges because of changes in federal requirements.The new federal requirements take into account Specialized Hauling Vehicles, or SHVs, and their ability to haul maximum loads allowed by law. SHVs are closely spaced, multi-axle, single-unit trucks that oftentimes consist of moveable axles that raise or lower as needed for weight, allowing them to carry higher loads concentrated over shorter distance. Examples include dump trucks, construction vehicles, solid waste trucks and other cargo-hauling trucks.
Resolution 2021-7 lists the county's weight-restricted bridges and those bridges impacted by the new federal regulations regarding SHVs.

The permit is available here. The permit is for single trips only unless otherwise indicated on the permit. A minimum of seven working days is needed to evaluate and perform an analysis if one has not been done before for the specific truck and bridge combination.
Federal regulations require that bridges subject to the National Bridge Inspection Standards (NBIS) receive a routine bridge inspection at least once every 24 months. Chelan County currently has 50 bridges subject to the NBIS that are open to vehicular traffic on its 647-mile road system. Some bridges warrant an inspection every 12 months based on their present condition.
A load rating report is performed for each bridge in the NBIS inventory by a professional structural engineer in accordance with federal and state regulations. A bridge load rating is the measure of the bridge’s load-carrying capacity. Chelan County has six NBIS bridges with weight restrictions.
Many vehicles like school buses, fire engines and ambulances are still allowed, depending on their weight and the loads they carry.
