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 will transform the existing interchange into a diverging diamond interchange. 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 and preliminary work associated with the new frontage road north of I-5.
  • I-5: Drivers can expect night lane closures and around-the-clock shoulder closures. Crews on occasion will detour I-5 traffic through the Marvin Road on- and off-ramps.
  • Marvin Road: Drivers can expect night lane closures, around-the-clock shoulder closures and narrowed lanes. When the weather cooperates, the northbound Marvin Road overpass sidewalk (on the east side of the bridge nearest to Nisqually) will close until further notice to pedestrians. Pedestrians will detour via the west sidewalk (nearest to Olympia). Please note the same sidewalk will also close to bicyclists. Bicyclists can use the full lane of Marvin Road or use the pedestrian detour.
