US 2 Grotto Vicinity Slope Stabilization

Project overview

In fall 2023, we built two debris flow fences on the north side of US 2 near milepost 44, or approximately four miles northwest of Skykomish. These fences will help mitigate risk to two culvert inlets, reducing the chances a potential debris flow from the Bolt Creek burn scar could clog them and send water, rocks and debris across the highway. We built a 6-foot-tall, 94-foot-long earthen berm a few hundred feet up the highway to redirect a potential debris flow away from US 2 in that area. Guardrail in the area was updated.

What to expect

Major construction on this project has completed. We will return in spring 2024 to add native seeds to help stabilize the area, but that work will not affect traffic.

Our crews built a 6-foot-tall, 94-foot-long berm to help mitigate risk from a potential debris flow following the 2022 Bolt Creek Fire.
