US 101 at milepost 246.37 at Tumwater Creek is closed for 80 days. The closure began Monday, March 3. The detour route is West Front Street/West 1st Street, Marine Drive and Tumwater Truck Route (State Route 117). A more detailed detour map can be found under the Maps & Drawings tab.
Project overview
This project removes and replaces several outdated culverts under US 101 and State Route 116 at Lees, Ennis, Tumwater and Chimacum Creeks. Washington State Department of Fish and Wildlife has identified these sites as barriers to salmon migration and other resident fish species.
WSDOT will replace outdated culverts with new structures for improved fish migration in the streams below as part of a statewide fish barrier correction program.
What to expect
The locations for culvert replacement are:
- US 101 at Lees Creek (milepost 250.5)
- US 101 at Ennis Creek (milepost 250.2)
- US 101 at Tumwater Creek (milepost 246.4)
- SR 116 at Chimacum Creek (milepost 0.22)
US 101 at Tumwater Creek closed on Monday, March 3. The closure length is 80 days. The detour route will be SR 117 for vehicles. Bicycles and pedestrians will use local roads to get around the closure.
Construction at Lees and Ennis Creeks on US 101 just outside Port Angeles begins Sunday, March 9. From 7 p.m. to 7 a.m. each night Sunday, March 9 through Thursday, March 13, the right lane will close in each direction of US 101 between South Del Guzzi Drive and South Brook Avenue. This will allow crews to set up the first stage of a traffic shift at each site. The speed limit at Lees and Ennis Creeks will be reduced from 40 mph to 25 mph during construction.
There will be no daytime lane reductions at Lees and Ennis Creeks.
Work on Chimacum Creek will begin in the summer of 2025. Travelers can expect a long-term closure of SR 116 at the creek between Shotwell Place and Chimacum Creek Drive. Travelers will use SR 19, Irondale Road and Chimacum Road to detour around the closure.
WSDOT and the design-builder will coordinate with local agencies and emergency services to minimize delays and keep people moving through work zones.
Crews will correct barriers to salmon migration under SR 116 at Chimacum Creek beginning in Summer 2024. Work on US 101 at Lees, Ennis and Tumwater Creeks will begin in 2025.
