Story

To enable the relining of an 80-year-old sewer line beneath the Lake Washington Ship Canal, a section of westbound Shilshole Avenue Northwest in Ballard will closed for four months beginning Jan. 20. 

The construction is part of King County’s Ballard Siphon Replacement Project to increase capacity in the regional sewer system and replace aging infrastructure.

For the duration of the closure, westbound traffic on Shilshole Avenue Northwest will be rerouted to Leary Avenue Northwest via 14th Avenue Northwest. Pedestrians and cyclists will be directed to Ballard Avenue Northwest. Eastbound traffic will be allowed Shilshole Avenue Northwest. There will be no parking on Shilshole Avenue near the project area for the duration of the relining work. (See map)

Access to businesses on Shilshole Avenue will be maintained at all times.

King County expects to complete the sewer system upgrade by spring 2014.

King County has budgeted $54.3 million for the project and received about $41.85 million in low-interest loans from the Washington State Department of Ecology’s State Revolving Fund and the Washington State Public Works Trust Fund to cover project costs.
