Work starts today near the Pacific County line to begin a culvert replacement on State Route 6, and drivers should expect some delays.

The Washington State Department of Transportation is advising anyone using SR 6 near Salmon Creek, west of Pe Ell, that work today will shift drivers to a temporary detour road to get around construction as part of the work.

According to WSDOT, contractor crews will be continuing work to replace a 6 ft. by 8 ft. box culvert that cross under State Route 6 with a new wider, 24 ft. span, four-sided box culvert , with the hope to provide for improved fish passage under the highway.

  • Monday, Aug. 12 to Thursday, Aug. 15: Travelers on both directions of SR 6 between mileposts 22.60 and 22.69 will alternate intermittently through a single lane with flaggers, daily from 6 a.m. to 4:30 p.m., for culvert replacement work. 
  • Tuesday, Aug. 13 until further notice: Travelers on both directions of SR 6, between mileposts 22.60 and 22.69, will be shifted onto a temporary single-lane, bypass road. This detour allows travelers to safely bypass construction around-the-clock, and will be controlled with an automated signal.  
  • Note: Travelers should expect delays of up to 20 minutes, for additional intermittent, daytime single-lane closures, as needed. 

During the work, anyone traveling the road will be shifted onto a temporary road around the clock, with an automated signal directing traffic flow. 

The speed limit will be reduced to 25-mph, throughout the work zone. Travelers should expect delays of up to 20 minutes, and may encounter intermittent, daytime, single-lane closures.

Shifting traffic to a temporary single-lane road allows travelers to safely bypass construction, and reduces delays.
