A single-lane detour will be in place during construction starting Oct. 2

TOUTLE – It is the time of year when we see many changes in the weather and the colors of leaves. Beginning Monday, Oct. 2, users of State Route 504 at Wooster Creek, east of Toutle, will see changes to their drive as well.

Washington State Department of Transportation contractor crews will close lanes of SR 504, also known as Spirit Lake Memorial Highway, at Wooster Creek, and build a temporary detour route.

“Replacing the aging and failing culvert with a wider concrete bridge span will improve fish passage, and improve safety to users of the highway,” said WSDOT Project Engineer, Devin Reck. “During heavy seasonal rains, the existing culvert becomes a choke point for storm water, and forces excess water over the roadway. Replacing the culvert will improve drainage and create a natural state for fish passage.”

During construction, Hamilton Construction Company will remove the 54-inch culvert, and build a 20-foot span bridge on SR 504. Once complete, the new structure will allow crews to build a natural creek bed under the highway with an easier water flow for improved fish passage.

While the highway is closed, traffic will shift to the north side of the road, onto a temporary single-lane, bypass road. This detour allows travelers to safety bypass construction around-the-clock, and will be controlled with an automated signal.

This $4.8 million project is scheduled for completion in fall 2018.
