The Cross Kirkland Corridor (CKC) trail between Northeast 52nd Street and 108th Avenue Northeast is closed. are repairing a culvert, building a retaining wall, and stabilizing a nearby stream. The damaged culvert runs under the County’s Eastside Interceptor Section 14 (ESI 14) sewer pipe. Construction work is extensive, and the closed section is not safe for pedestrians.
Crews will divert sewer flows to a temporary above-ground pipe during construction. This work will help protect the pipe from potential damage in the future.
Please follow the detour signs and stay out of the work area.

ESI 14 sewer pipe is a 7-foot diameter pipe owned by King County. The pipe carries about 2.6 million gallons of wastewater a day during dry weather to the County’s South Treatment Plant in Renton. In July 2025, King County and City of Kirkland crews found a leak from the County’s ESI 14 sewer pipe that was entering the culvert. King County coordinated with Public Health – Seattle & King County, and no public health risk was identified.
Crews completed repairs to the ESI 14 sewer pipe in February. Work to build a new retaining wall and repair the culvert will finish by the winter. Crews will remove the diversion pipe and restore the site after the repairs are complete.
The Eastside Interceptor is one of the largest conveyance pipes in our regional sewer system. It collects and carries untreated wastewater from local municipal sewer systems between Kirkland and Renton and sends it to South Treatment Plant, where it is cleaned and released into Puget Sound.
To stay informed about the project, please visit the Eastside Interceptor Section 14 joint rehabilitation project webpage.
