Construction begins this summer on new I-5 Chamber Way overpass in Chehalis Temporary bridge to keep traffic moving CHEHALIS – Work on a new Chamber Way overpass above Interstate 5 in Chehalis will begin by the end of July.

The Washington State Department of Transportation awarded a $10.9 million contract to Quigg Bros., Inc. of Aberdeen to design and build a new wider, taller overpass. The project will replace the bridge damaged by an unpermitted, overheight load on July 22, 2016.

“This project means a lot to this community, and we’re excited to move forward,” said WSDOT project engineer Frank Green. “It’s important to get this work done quickly, while reducing the impact to traffic on Chamber Way and I-5.

The contractor’s proposal for replacing the Chamber Way overpass includes constructing a temporary bridge over I-5 on the north side of the current structure. That work will begin by the end of July, with traffic scheduled to shift over by the fall. The existing overpass will then be demolished, and crews will build a new one in the same footprint.

The new structure will be at least 16 feet 6 inches above the freeway, a height consistent with current design standards.

The 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. This year, the Legislature advanced a portion of those funds to speed up the replacement of the Chamber Way overpass. Emergency relief funds from the Federal Highway Administration also will be used for this project.

Construction of the overpass will be complete by fall 2018.
