Larger culvert will create more natural stream, open additional 2.8 miles of habitat for fish

ARLINGTON – A project to replace a culvert that blocks access for salmon and other fish in Schoolyard Creek will mean up to four weeks of traffic delays for people who travel on State Route 530 between Arlington and Darrington.

Beginning Saturday, July 27, contractor crews from Kiewit, working for the Washington State Department of Transportation, will temporarily reroute the highway onto a single-lane bypass near Lind Road east of Arlington.

People traveling on that part of SR 530 should expect traffic delays of 5 to 10 minutes between Arlington and Darrington, from July 27 to Tuesday, Aug. 20. Temporary traffic signals will control vehicles using the bypass.

The single-lane bypass for SR 530 will be in use 24 hours a day, seven days a week. Kiewit will monitor traffic backups and coordinate with local events to optimize traffic signal timing and minimize delays for travelers.

While people are using the bypass, the contractor crews will remove an old, narrow culvert that blocks fish passage and replace it with a larger culvert with a natural streambed. This will allow water to flow more smoothly and open up 2.8 miles of habitat to salmon, steelhead and trout.

The new fish passage helps WSDOT fulfill a U.S. District Court ruling requiring the replacement of about 1,000 culverts blocking fish passage under state roads. This will help restore fish habitat.

Another project to replace a small culvert at Trafton Creek along the same stretch of SR 530 has been postponed until summer 2020. WSDOT has asked the contractor for a new design to make the new culvert easier to maintain. When the project is finished, it will make an additional 3.5 miles of habitat available in the creek for resident and migratory fish.
