Ballard Siphon project update: Shilshole Avenue NW westbound lane to re-open this week, ahead of schedule

Information provided by King County Wastewater Treatment Division

King County’s contractor finished work on the 80-year old sewer pipe in south Ballard about a month ahead of schedule.

Shilshole Avenue N.W. will be fully open to traffic on the night of Friday, April 4.

The work had closed the Shilshole Avenue N.W. westbound lane near N.W. Dock Place since January.

The contractor put a new lining in the pipe. The new lining will help keep the pipe working to serve north Seattle into the next century.

The sidewalk detour will stay in place until the project is finished later this spring. Pedestrians should continue using Ballard Avenue Northwest to move around the site (see map in attached).

King County appreciates the community’s patience during this work.
