SR 20 North Cascades Highway re-opened between Newhalem and Rainy Pass. Trails, camping, and recreation were closed as firefighters fight the Sourdough Fire.

The Washington State Department of Transportation in partnership with Sourdough Fire Incident Northwest Management Team 10 and National Park Service re-opened State Route 20/North Cascades Highway from milepost 120 in Newhalem to milepost 156 just west of Rainy Pass located 45 miles west of Winthrop, at 9 am on Wednesday, August 9th.

Travelers along SR 20 are advised they may encounter firefighting personnel and apparatus working along the highway. Traffic control is in place for the safety of the traveling public and should be observed. Stopping along this stretch of highway is not permitted. This remains an active fire area and the road is subject to close again with little notice based on fire behavior or firefighting mitigation strategies. People are encouraged to plan ahead for unexpected closures and travel delays.

The North Cascades Visitor Center in Newhalem is open daily. The National Park Service has closed camping, trailheads, overlooks, pullouts, and other recreation east of Newhalem, due to the Sourdough Fire. Additional details about trail, area and camp closures are available on the North Cascades National Park Service Complex website.

SR 20 closed at 10 pm on Friday, August 4th to support firefighting efforts along the highway. WSDOT crews will continue to partner with the Sourdough Fire Incident Management Team. Road closure information is posted in the WSDOT real-time travel center and @wsdot_north on X/Twitter and updates will be provided as available.

Also, westbound SR 96 near Mill Creek will close Aug. 10-15th for fish passage installation. Lane reductions of eastbound and westbound SR 96 will continue through Aug. 19th. All westbound lanes of State Route 96/128th Street Southeast will close and only one eastbound lane will remain open during the first phase of a series of closures beginning Thursday night, Aug. 10th near Mill Creek.

While the westbound lanes are closed, contractor crews working for the Washington State Department of Transportation will install a new culvert for the North Creek fish passage project northwest of Mill Creek. It will be the last of three full closures of westbound SR 96 for this work.

The first phase of the work, when the north half of SR 96 is closed and the first half of the new culvert is installed, begins at 7 pm, Thursday, Aug. 10th, and will last until approximately 1 am. Tuesday, Aug. 15th contractor crews will then swap sides to install the south half of the culvert during the second phase of the closure. A single lane of SR 96 will remain open in each direction during this phase, which will wrap up by 4:30 am Saturday, Aug. 19th.

First phase: Beginning at 7 p.m. Thursday, Aug. 10, until 1 a.m. Tuesday, Aug. 15, no westbound traffic will be allowed on SR 96 west of Elgin Way/Dumas Road through the work zone north of McCollum Park. Eastbound traffic will be reduced to one lane.

A 6.5-mile signed detour will lead people traveling on westbound SR 96 around the closure using southbound SR 527, westbound 164th Street Southeast and northbound Interstate 5. People should plan for additional travel time.

Second phase: Beginning at approximately 1 am Tuesday, Aug. 15th, one westbound lane of SR 96 will reopen. One eastbound lane of SR 96 also will remain open and shift to the usual lefthand lane of westbound SR 96, while the center and usual eastbound lanes will close. People should continue to expect delays and seek alternate routes until work concludes at 4:30 am Saturday, Aug. 19th.

During the closures, crews will install a 25-foot-wide concrete box culvert and build a natural creek bed, replacing a 36-inch pipe that prevents fish in North Creek from passing beneath SR 96. Once installed, the new fish passage will open almost 2.5 miles of additional habitat to native fish species, including Chinook, coho, steelhead, searun cutthroat and resident trout.
