Crews will soon kick off an effort to add a new roadway surface to several areas of State Route 8 between Elma and Summit Lake in Thurston County. In addition to the highway, crews also will repave the westbound and eastbound SR 8 exits to US 12 Oakville/Centralia in Elma.

The work will begin Monday, July 15 and continue into fall.

What this means for travelers

  • Daytime travelers will see single-lane closures in each direction.
  • The Washington State Department of Transportation will lower the current 60 mph speed limit to 35 miles per hour when construction activities require lane closure.
  • Ramp paving will require night closures. WSDOT will announce when this closures are scheduled.
