A weight limit on the 170th Avenue bridge over Beaverton Creek was approved by the Washington County Board of Commissioners during its regular meeting Tuesday. 

This restriction comes after a load rating by the Oregon Department of Transportation determined a restriction was needed. Posted weight limits are enforced by the Washington County Sheriff’s Office Motor Carrier Officers.

The weight limit will stay until the bridge is repaired or replaced. The bridge is included in the 170th Avenue project to build new sidewalks, pedestrian crossings, street lighting and a center turn lane from Alexander Street to Merlo Road. The project has only received funding for design and right-of-way acquisition.

Of Washington County’s 184 bridges, 13 are now weight limited. The bridges are safe for vehicles not exceeding the posted weight limits.

Washington County is committed to planning, building and maintaining a great transportation system, ensuring the safety of all roadway users and operating the County roadway system in a cost-effective and environmentally responsible manner.
