Suiattle River Road Project
The Suiattle River Road project was completed on October 10, 2014.
Major flooding in 2003 and 2006 closed Forest Highway 26, known as the Suiattle River Road, at mile post 12.5.
This Federal Highway Administration made the following repairs at Sites 1 - 5 and the US Forest Service made the repairs at Sites 6 - 8. Click on the "Who Did What" link below to find out more about these repairs:
- Site 1 - Milepost 6.0: Rerouted the road for about 2500 feet, with realignment of about 375 to 400 feet inland from the eroded Suiattle River bank. The old roadway was abandoned and rehabilitated with mitigations for associated wetlands and flood plain reconnection.
- Site 2 - Milepost 12.6: Reconstructed the road 1200 to 1300 feet, with an offset of up to 70 feet from the existing road.
- Sites 3 & 4 - Milepost 13.0 and 13.4: Rerouted around the two washouts with a realignment of approximately 1.1 mile of road upslope of Road 26 and away from the Suiattle River.
- Site 5 - Milepost 14.4: Aligned the roadway for a length of about 900 feet, 55 to 90 feet away from the eroded river bank; re-established the Huckleberry trailhead and parking; and abandoned and rehabilitated the temporary reroute road.
- Site 6 - Milepost 20.8: Widened the roadway into the hillside for about 250 feet.
- Site 7 - Milepost 20.9 (Downey Creek Bridge): Removed the existing embankment and culvert at the first approach for 210 feet and built a three span bridge extension to replace that embankment and created a wider channel opening.
- Site 8 - Milepost 22.9 (Sulphur Creek Bridge): Built a concrete faced retaining wall at the first approach to replace the failed embankment and created a wider channel opening.
