WICKERSHAM – Drivers on State Route 9 should plan for a full weekend closure of the highway near the Whatcom-Skagit county line starting at 8 p.m. Friday, Sept. 13.
The full closure will be preceded by three days of single-lane closures and minor delays while crews start work on a culvert replacement project to improve fish passage underneath SR 9.
Drivers can expect single-lane traffic and flagging starting tomorrow, Sept. 11, through Friday, Sept. 13, from 7 a.m. to 5 p.m. daily.
At 8 p.m. Friday, Sept. 13, crews will close both lanes of SR 9 between Royer Street and NP Road to remove the existing culvert and install a new, larger culvert. Crews will reopen the highway to single-lane traffic by 5 a.m. Monday, Sept. 16.
During the weekend closure, signs will direct drivers at various locations along SR 9 – from SR 542 at Nugent’s Corner to Sedro-Woolley – to alternate routes.
After another week of flagger-controlled lane closures, road crews should wrap up most of the work on the highway. The project is expected to be complete by the end of September.
Contractor Stremler Gravel Inc. of Lynden won the $351,486 contract to replace the existing culvert underneath SR 9 with a wider, deeper structure that will simulate a natural stream bed and enhance fish passage.
The project will open up spawning grounds to coho salmon and cutthroat trout that use NP Creek, a tributary of the Samish River. The project will also improve habitat access for other fish species in the Samish River, including steelhead trout, bull trout, and chum salmon.
Travelers should check the Construction Update Report for more information about the closures.
