Snoqualmie River embankment repairs this summer ensures protection of highway, trail

Summary

Crews will soon begin maintenance along a stretch of the Snoqualmie Valley Trail. Trail users should expect closure of the trail section to run from June 1 to Oct. 31.

Story

Vital repairs to a damaged structure along the Snoqualmie River that protects a state highway, a fiber optic line, and a King County regional trail from river erosion is expected to begin in early June.

Work to rebuild the Sinnema Quaale Upper Revetment between Carnation and Duvall requires closing a stretch of the Snoqualmie Valley Trail from approximately 1-½ miles south of Northeast 124th Street to 2 miles north of the Stillwater Natural Area.

The trail closure is expected to run from June 1 to Oct. 31, and no trail detour is available. Trail users are encouraged to take advantage of other portions of King County Parks’ 175-mile regional trail system.

The aging revetment – which absorbs and deflects the Snoqualmie River’s erosive energy – has been repeatedly damaged by flooding.

Rebuilding the revetment includes reconstructing about 750 feet of bank, and rebuilding approximately 1,100 feet of the adjacent trail. The $6.3 million project is being funded primarily by the King County Flood Control District, with King County Parks providing funding for rebuilding the trail.
