Beginning Monday, Jan. 20, westbound traffic on Shilshole Avenue Northwest will be detoured to Leary Avenue Northwest for approximately four months. This week SDOT reassessed the traffic detour based on community feedback and revised the detour route as shown in the map on the project website. The new route directs westbound traffic to 14th Avenue Northwest, Northwest Leary Way, Northwest Market Street and south on Shilshole Avenue Northwest.
The detour is necessary to reline the existing 80-year-old Ballard Siphon sewer line that runs underneath Salmon Bay. Access to businesses on Shilshole Ave NW will be maintained at all times.
Westbound bicycles and pedestrians will be detoured to Ballard Avenue Northwest and should follow posted detour routes. Eastbound traffic will remain on Shilshole Avenue Northwest.
Please use caution when traveling through work areas, follow posted traffic signs, cones and flaggers and plan for extra travel time when commuting.
What to Expect During the Detour:
- Westbound traffic detoured to Leary Ave NW for four months
- Traffic control signs
- Increased truck traffic along detour route
- Parking restrictions along detour route
- Access to businesses on Shilshole Ave NW will be maintained at all times
