Sammamish River Trail detour routes
King County will close sections of the Sammamish River Trail between NE 85th Street and NE 51st Street to install the new sewer pipe when construction starts in 2021. We’ve been working on preliminary detour routes based on direction we’ve received from the City of Redmond, King County Parks, and your feedback. Learn more about preliminary detour routes .

Project description
The Lake Hills and NW Lake Sammamish sewer pipe has been serving Redmond and Bellevue for 50 years. The water you use travels down your drain to City sewer systems. The City’s pipes send wastewater to King County’s sewer system where it is carried to the Brightwater Treatment Facility in Woodinville for treatment.
King County is working on a project to upgrade 4.5 miles of this sewer pipe. King County will build the new pipe in trails, roads and parks in Redmond. This project is necessary to meet the needs of your growing community. Construction is expected to begin in 2021 and may impact your daily routine. When complete, the new pipe will provide sewer service for 50 years or more.
