Project overview
In December 2025, a flooding event from Boise Creek just west of Enumclaw damaged State Route 410 at milepost 26.6. The road was closed Dec. 10, 2025 after the eastbound lanes were washed away. On Dec. 16, the road was reopened in a single-lane alternating traffic configuration using the westbound shoulder of the roadway, controlled by a temporary traffic signal.
Construction crews began roadway and streambed repairs Dec. 22. The construction completed and the road reopened Dec. 23.
What to expect
Construction finished in December 2025. Travelers should not expect additional travel delays for this project.
SR 410 was damaged by flooding along Boise Creek at milepost 26.6.
SR 410 connects SR 167 in Puyallup/Sumner to US 12 in Naches, via Chinook Pass. It provides access to Mount Rainier National Park and the Mt. Baker-Snoqualmie National Forest, as well as the Crystal Mountain ski area. This section of the highway averages about 3,000 cars daily, but traffic can vary widely during the seasons.
