SR 109 near Hoquiam to close around the clock for three weeks March 22

13-mile detour will be set up as crews stabilize hillside along highway

HOQUIAM – Travelers who use State Route 109 through Hoquiam should factor in extra travel time starting the week of March 20. That’s when about a half mile of highway will close in both directions for three weeks west of the SR 109 Spur for slope stabilization work.

Prior to the full closure beginning Wednesday, March 22, there will be daytime lane closures for two days as crews bring in equipment and install signs and fencing.

7 a.m. to 5 p.m. Monday, March 20, and Tuesday, March 21

  • Plan for travel delays as SR 109 between Grays Harbor Boulevard and the SR 109 Spur will be reduced to one alternating lane of traffic in one direction at a time.

What to expect during three-week closure

At 7 a.m. March 22, crews will close the highway around the clock for three weeks. During the closure, all travelers will follow a signed 13-mile detour via Powell Road, Ocean Beach Road and US 101. This could add up to 30 minutes of travel time for people who live or work just west of the closure when going to and from Hoquiam.

Slide-prone section of highway

A steep limestone hillside above SR 109 has a history of tree-filled debris slides. After a slide, an engineering geologist must inspect the hillside and it can sometimes take several days to clear the highway.

Washington State Department of Transportation contractor crews from Rognlin’s, Inc. will remove trees of concern, debris and rocks from the hillside. This project will help reduce the potential for extended highway closures in the future.

WSDOT recognizes there is no good time to close a highway and appreciates travelers’ patience during this important work.

Grays Harbor travelers are encouraged to sign up for email updates. Real-time traffic information is available on the WSDOT app and WSDOT Travel Center Map.

Slow down on ice and snow.

It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.

Carry chains, practice installing them.

Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.

Pack your winter car kit.

Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
