- Complete List of Road Restrictions in Chelan County (Updated May 30, 2017, at noon)
Several bridges in Chelan County are under weight restrictions at this time. For these bridges, the gross weight for vehicles must not exceed the limits set forth by the laws of the State of Washington. 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. Resolution 2017-20 lists these bridges and their current load restrictions:
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 were introduced by the trucking industry in the last decade. These trucks 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.
Since the 1975 adoption of the American Association of State Highway and Transportation Officials family of three truck configurations carrying legal loads, the trucking industry has introduced specialized single-unit trucks with closely spaced, multiple axles that make it possible for these short-wheelbase trucks to carry maximum loads of up to 80,000 pounds and still meet the Federal Bridge Formula equation, called Formula B.
The AASHTO truck configurations selected in 1975 that match the Formula B equation do not represent these newer axle configurations. These SHV trucks cause compression and tension in bridges that exceed the stresses induced by the AASHTO Type 3, Type 3S2 or Type 3-3 legal vehicles by over 50 percent in certain cases, according to the federal government. The shorter bridge spans are especially sensitive to the newer SHV axle configurations.
The Federal Highway Administration requires every public bridge owner to post bridges for SHVs that do not pass a load rating analysis for these vehicles, in addition to the current standard legal vehicles. Those county-owned bridges in Chelan County that are impacted by the new federal regulations are listed in the resolution.
