Construction

I-5 - SR 510 Interchange - Reconstruct Interchange
Highway:
I-5 Region: Olympic County: Thurston Location: Milepost(s) 111
Contact: Doug Adamson, 360-357-2716
Description: Crews working for WSDOT will transform the existing interchange into a diverging diamond interchange. In addition to helping drivers, pedestrians and cyclists will also see improvements.

All users of this interchange are strongly encouraged to sign up to receive WSDOT email updates.

The first phase of work is to demolish a segment of the overpass. For the safety of the traveling public, the work will require lane closures on I-5 under the overpass during night hours. WSDOT also will detour I-5 traffic through the Marvin Road on- and off-ramps. 

During this first phase, which will continue into 2019, WSDOT expects to keep all lanes open on Marvin Road itself. Drivers can expect shoulder closures and narrowed lanes. Pedestrian and bicycle access on Marvin Road will remain open.

The first phase of work will also require I-5 shoulder closures below the overpass and shoulder closures of the southbound I-5 exit to Marvin Road.

Work schedule: Around-the-clock daytime shoulder closures and night I-5 lane closures.
