Starting as early as Monday, January 5, 2026, the Cross Kirkland Corridor (CKC) trail between Northeast 52 Street and 108 Avenue Northeast will be close to the public.
King County Wastewater Treatment Division anticipates that construction will last through February 2026. We will provide advance notice of construction activities and future trail openings through web bulletins, emails, and text messages for project subscribers.
For your safety, do not enter the closed section of the trail. Heed all signs and follow the detour as outlined in the map below.
Crews installed a 3,000-foot above-ground temporary 18-inch pipe to divert the wastewater. They dug in two locations on each side of the leaking joints to connect the sewer flows to the above-ground temporary diversion pipe.
- Wastewater flows will be diverted to the above-ground pipe using a bypass pump with four generators to maintain sewer service for the community.
- While flows are diverted above-ground, crews will enter the empty 7-foot diameter underground ESI 14 pipe to repair the leaking joints.
- Once repairs are complete, crews will restore flows to the ESI 14 underground pipe, remove the above-ground temporary pipe, and restore the trail.
ESI 14 sewer pipe is a 7-foot diameter pipe, which carries 10 million gallons of wastewater a day on average during dry weather. In late July 2025, King County and City of Kirkland crews detected a leak from the County’s ESI 14 sewer pipe that was entering Kirkland’s piped stream. King County coordinated with Public Health – Seattle & King County, and no public health risk was identified.
In September 2025, King County Department of Natural Resources and Parks issued a Declaration of Urgency to expedite the repair efforts. The City of Kirkland also issued a Proclamation of Emergency to aid in repairs.
Since September, King County crews and contractors have been repairing the section of CKC Trail between NE 52nd Street and 108th Avenue NE. Repair work consists of installing a temporary above-ground wastewater diversion, repairing the joints inside the underground 7-foot diameter pipe, and restoring the construction site.
