Snoqualmie Valley Trail reopened as Sinnema Quaale project nears completion


Just in time for the additional hour of daylight, the Snoqualmie Valley Trail in the Stillwater area between Duvall and Carnation is once again open to foot and bicycle traffic.


Sinnema Quaale project nears completion

The Snoqualmie Valley Trail was temporarily closed last June for safety reasons during construction work to repair approximately 1,100 feet of Snoqualmie River bank erosion and slope instability.

I want to thank everyone for their patience during this critical project.  Now we can all appreciate the increased safety to our road and other infrastructure,” said King County Flood Control District Supervisor Kathy Lambert.

The area, also known as “car body curve,” sustained significant damages in the November 2006 storm and had been further damaged by subsequent high river flows over several years.

The record wet winter and multiple flood events delayed the project and reopening of the trail. As a result, a short period of follow up construction will be necessary over several weeks this summer which may temporarily impact trail usage.

The 31.5-mile Snoqualmie Valley Trail is managed by King County Parks and meanders past working farms as well as preserved open space areas, and connects to the cross-state John Wayne Pioneer Trail in Iron Horse State Park. Points of interest include Tolt-MacDonald Park, Meadowbrook Farm, Three Forks Natural Area and the Tokul Trestle.

Final construction work will include State Route 203 paving and guardrail repairs, final resurfacing of the Snoqualmie Valley Trail, installing permanent fencing next to the trail, and replanting the site.
