This project provides for the improvement of fish passage in two locations along SR 20 in the town of Concrete, located in Skagit County - one at Fish Creek (MP 87.82) and one at Lorenzan Creek (MP 88.78) by replacing existing culverts with two buried fish passage structures.
What to expect
This project will temporarily occupy the Cascade Trail to divert SR 20 traffic around the construction work zone for up to 21 days in summer of 2021. During construction, 2,100 linear feet of the trail will be closed to the public to protect their safety. WSDOT will provide a detour for bicycles and pedestrians during the closure that is 0.65 miles long along town streets and sidewalks already suitable for pedestrians and bicyclists.
Travelers in this area of SR 20 can expect a single lane with alternating traffic with a flagger or temporary signal seven days a week, 24/hours per day during construction.
