Trail alert: Cedar River Trail

Essential repair project leads to closure of half-mile stretch of Cedar River Trail

Work to curb erosion from the Cedar River that threatens a state highway and major fiber optics cable requires a month-long closure of a portion of King County’s Cedar River Trail in Maple Valley.

Beginning Monday, July 8, a half-mile-long portion of the Cedar River Trail will be closed to all users from the trail’s intersection at 16916 Renton-Maple Valley Rd. S.E. to the trail’s intersection at 201st Place Southeast.

Heavy construction equipment will be using the trail during the project. Because of the trail’s close proximity to both the river and State Route 169, no designated detour around the closed portion of the trail is available. Recreational trail users are encouraged to plan around the closed section or seek other portions of King County’s 175-mile regional trail system during the month-long closure of this stretch of the Cedar River Trail.

The upcoming work, known as the Belmondo Revetment Enhancement Project, includes placing large rock along the river’s edge and building up the bank to curb river erosion that threatens a major fiber optic cable, the Cedar River Trail and State Route 169.

The work is expected to cost $513,000 and will be completed by Road Construction Northwest. The trail will reopen in late September.

More information about the Belmondo Revetment Enhancement Project, made in possible in part by funding from the King County Flood Control District, is available at, or by contacting Mason Bowles with the King County Department of Natural Resources and Parks, at 206-296-8736;
