SR 109 in Grays Harbor County Remains Closed Due To Mudslide

Submitted by Washington State Department of Transportation

State Route 109 west of Hoquiam in Grays Harbor County remains closed after a large mudslide swept across the highway during the afternoon of Sunday, January 17. Currently, there is no estimated timeframe for reopening the highway.

The Washington State Department of Transportation plans to issue an emergency contract to address this work.

WSDOT geotechnical engineers estimate the slide is 300 feet long and up to 90 feet high. Approximately one-third of the slide debris is on the highway or in the bay. Another two-thirds of the debris is detached from the hillside above SR 109, but is still up on the slope.

Updates on debris removal and when the roadway might reopen will be shared on the WSDOT blog. WSDOT has shared images of the slide on Flickr.


A detour is in place around the slide area using Powell Road, Ocean Beach Road, US 101 and the SR 109 Spur.

  • Northbound SR 109 is closed at SR 109 Spur. Local access is available on northbound SR 109 from SR 109 Spur to Grays Harbor Boulevard.
  • Southbound SR 109 is closed at Powell Road. Local access on southbound SR 109 is available up to Grays Harbor City Court.
