Pipeline construction to require temporary closure of 32nd Ave W


Beginning Thursday, March 1, King County sewer utility crews will temporarily close a portion of 32nd Avenue West in Seattle’s Magnolia neighborhood for about five weeks as part of a project to repair a damaged pipeline.


A pipeline repair project in Seattle’s Magnolia neighborhood will require temporary closure of a portion of 32nd Avenue West between Clise Place West and 33rd Avenue West starting on Thursday, March 1.

The five-week closure will enable contractors to assemble pipeline segments into a single unit that will be pulled through the existing tunnel over a three-day period scheduled for early to mid-April.

Work is scheduled weekdays from 7 a.m. to 6:30 p.m. and occasional Saturdays between 9 a.m. and 6:30 p.m., with activity going to a 24-hour work schedule during the three-day pipeline pull, as it must be completed without stopping.

King County and the contractor are taking measures to reduce inconvenience to project neighbors, and will work closely with residents who may be impacted by construction activities.

People with immediate concerns can call a staffed 24-hour construction hotline at 206-205-5969, or visit the project’s online open house at to learn about construction activities and submit comments.
