CHEHALIS – A permanent replacement for the temporary Chamber Way bridge over Interstate 5 in Chehalis is one step closer. Today, the Washington State Department of Transportation announced plans for a new overpass that will begin construction next year.

WSDOT evaluated long-term possibilities for the overpass that was severely damaged by an oversized load in July, and will move forward with a project to build a four-lane structure with bicycle and pedestrian access. The new overpass will be at least 16 feet 6 inches above the freeway, a height consistent with current design standards.

“This community-focused solution would not be possible without the support from legislative leadership and our federal transportation partners,” said Roger Millar, secretary of transportation. “With their concurrence we can now deliver this new overpass in a timely manner and keep people moving safely for years to come.” 

A new overpass is part of a larger project in the Connecting Washington transportation funding package that includes improvements to I-5 and the adjacent intersections. Funding for design of the larger project is available in 2019. Based on support from legislative leadership for advancing a portion of those funds, WSDOT is moving forward with plans to speed up the replacement of the Chamber Way overpass. Emergency relief funds from the Federal Highway Administration will be also be used for this project. 

Next steps
WSDOT will meet with members of the community in the coming weeks to discuss the overpass replacement project and gather feedback to help minimize potential construction impacts. Specific dates and locations will be announced soon. The agency will advertise the design-build contract for competitive bid next year, with construction to begin soon afterwards.
