I-5 Fort Lewis Weigh Station Study

Planning study news

The study of the I-5 Fort Lewis Weigh Station is complete and the report is available for viewing.

August 2020 - June 2021


The Fort Lewis Weigh Station located along northbound Interstate 5 near DuPont in Pierce County is in need of updating. Freight traffic in the area experiences recurring congestion and delay due to high volumes from both freight and commuter traffic. The weigh station was built in 1969 and in 2020 it was the second highest used weigh station in the state. In collaboration with federal, state, local and tribal partners, WSDOT developed a list of recommendations for operation and infrastructure improvements to the weigh station.
