WHAT: A City of Kirkland contractor begins the 10-month process in late February to upgrade an aging water and sewer main along 108th Avenue Northeast.
Marshbank Construction is replacing the two systems—both more than five decades old—to increase their capacities to serve Kirkland’s growing population and to reduce the systems’ needs for maintenance.
That need is most urgent in the sewer line, which runs from Northeast 68th Street to Northeast 53rd Street. Settling soil has created a sag in the sewer line, allowing sewage to accumulate there and requiring maintenance crews to periodically flush the line.
The contractor is also replacing the water main between Northeast 68th and 60th streets.
WHEN: Marshbank’s crews will work 9 a.m. to 3 p.m., Monday through Friday, starting in late February or early March.
- Marshbank will work several nights in 108th Avenue Northeast’s intersection with Northeast 68th Street to connect the water and sewer mains and to pave.
WHAT TO EXPECT: Marshbank will pave the entire width of 108th Avenue Northeast this fall between Northeast 68th and 60th streets.
Between Northeast 60th and 53rd streets, the contractor will pave the center turn lane and southbound lane. Weather could force the contractor to delay its paving schedule until spring 2021.
- King County Metro will re-route some buses around construction zones.
- Marshbank will detour traffic around any closed sections of road and will shift travel lanes to accommodate construction zones.
- The contractor will maintain access for local residents, mail, emergency responders and waste management.
