Single-lane closures scheduled through August

COUGAR – Travelers who use State Route 503 and the SR 503 Spur through Cougar should plan for delays through the end of August as road improvement work continues.

On Monday, Aug. 20, Washington State Department of Transportation’s contractor, Granite Construction Co., will continue preservation work to repair damaged portions of the highway. The roadway will then be resurfaced with a new layer of asphalt to protect the road with a watertight bond. 

“Because of wear and tear and weather, the road isn’t in great shape – there’s a fair amount of rutting, deterioration and cracking,” said Susan Fell, WSDOT project engineer. “This work will extend the life of the highway and reduce the need for costly maintenance and emergency repairs.”

To resurface the road, Granite Construction Co. will use a chip-sealing treatment made of asphalt and crushed rock. To prevent vehicles from kicking up loose rock, flaggers will alternate single lanes of traffic in either direction, and travelers will follow a pilot car, around-the-clock. Travelers should expect delays of up to 20 minutes and a reduced speed limit through the work zone. Motorcyclists should use extreme caution due to loose gravel on the roadway.

Once resurfacing has cured, crews will stripe and add pavement reflectors set into the surface of the roadway, which hold up to winter weather and snow plowing better than reflectors installed on top of the pavement.

Closure details:

  • When: 6:30 a.m., Monday, Aug. 20, through 7 a.m. Thursday, Aug. 23
  • Where: Travelers on both directions of SR 503/SR 503 – Spur, between Northeast Rock Creek Road and Williams Road, will alternate through a single lane around-the-clock, with flaggers and pilot car, for chip seal work.

This work is part of the $5.3 million SR 503 – Spur – Chip Seal and SR 503 Rock Creek Rd. to Williams Rd. project to preserve the highway between Clark and Cowlitz Counties. This work is expected to be completed this fall. All work is weather dependent.
