Plan for delays on US Highway 101 near Siebert Creek

Construction to improve fish passage along US Highway 101 at Siebert Creek between Sequim and Port Angeles is expected to cause traffic delays later this month.

Beginning Tuesday, March 30, contractor crews working for the Washington State Department of Transportation will set six 175-foot-long concrete bridge girders at Siebert Creek. Heavy machinery near the travel lanes will require crews to alternate traffic through the work zone with flaggers.

During the scheduled work activities, travelers should plan for delays of up to 20 minutes and consider alternate routes. Those who walk or roll will be accommodated and should expect brief delays.

The work schedule is slated for 9 a.m.-3 p.m. March 30, and Wednesday, March 31.

A restored Siebert Creek is projected to produce nearly 34 miles in potential habitat gain for migratory fish species. The westbound bridge is on track to be finished later this year.

Crews will work at both Bagley and Siebert Creeks through late fall of 2021.
