A half-mile stretch of the Snoqualmie Valley Trail between Duvall and Carnation will be closed July 5 to Aug. 12, as workers complete the Sinnema Quaale Revetment reconstruction project along the Snoqualmie River.

From approximately 1.5 miles south of N.E. 124th Street to 2 miles north of the Stillwater Natural Area, the trail will be closed to all use with no detour.

The work to be done will complete the river bank work started last summer to replace a failing revetment. Last winter’s record wet weather and multiple flood events delayed the completion of the project. Due to work being done in the water, construction is constricted to summer months when protected fish species are not present.

Construction activities will include repaving State Route 203 near the project site, guardrail repairs, trail resurfacing, installing fencing along the trail, and replanting the construction site.

The construction area, known as “Car Body Curve,” sustained significant damage during severe flooding in November 2006, with further damaged caused during subsequent floods over several years.

Work that began in 2015 and was completed earlier this year included improving protection for the state highway, regional trail and a regional fiber optic trunk line, and removing the remains of at least 20 rusted 1940s car bodies that several decades ago were placed along the river to curb bank erosion.
