Safety First

For the safety of pedestrians and transit operators, vehicle access between S 2nd St and S 3rd St and Logan Ave S and Burnett Ave S is for transit vehicles only. Personal vehicle access is not permitted.

Overall Construction Update

Current construction efforts are putting our completion ahead of schedule, with storm utility improvements now complete.

Remaining sewer utility work has reached 90% completion and will be completed this fall with low-impact, cured in-place lining happening through spring 2022.


Parking Sign

We are trying to minimize parking impacts as much as possible.

The City Center Parking Garage offers free parking for access to downtown businesses through December of this year and can also be used by residents during construction. The garage is accessible between 5 a.m. and 11 p.m., Sunday through Thursday, and from 5 a.m. to 1 a.m. on Friday and Saturday. Overnight parking is allowed during our construction efforts, but please note that all garage doors are locked outside of these hours. In addition, street parking is available on S 3rd St.

Traffic Detour and Large Deliveries

During installation of the utilities, there will be times when it is not safe for traffic to proceed through the work zones. As a result, full or partial road closures with detours can be expected during different phase of the project. We will provide detailed updates of closures and detours as construction progresses.

While these detours are necessary for completion of the project, we do want to ensure that businesses are still able to operate and receive product deliveries essential to their operations. If you are currently impacted by road closures or detours and have an upcoming product delivery, please call 425-363-1007 for help with coordination of deliveries larger than a single unit.

S 2nd Street Detour Route

While work is occurring on S 2nd St between Morris Ave S and Shattuck Ave S, the two lanes north of the center island will remain open to traffic, while the two lanes south of the center island will be closed. Access to and from Morris Ave S and Shattuck Ave S will be set up through the intersections from north of the center island. Access to and from Whitworth Ave S will be maintained during work hours but limited to when flaggers are at the intersection. Follow posted signage and flaggers for access.

S 2nd Street Daytime Access

Due to the lack of a traffic signal at the intersection of Whitworth Ave S and S 2nd St, access to and from Whitworth Ave S at S 2nd St will be closed overnight. Drivers will need to access Whitworth Ave S from S 3rd St, as shown on the map.

S 2nd Street Nighttime Route

Once we’ve completed sewer utility work Whitworth Ave S to Shattuck Ave S, we will move the work area north of the island and move west towards Rainier Ave S. Please follow posted signage and flaggers during shifts in access.

Related Downtown Projects

The South Wells Avenue and South Williams Avenue Conversion Project is under a separate contract but will likely be conducted in the same timeframe. This project will improve intersections, add new signals, and convert both streets to two-way operations.

The adopted Civic Core Action Plan explores ways to pedestrian and bicyclists facilities and enhancements, traffic operation and circulation improvements to Downtown. The improvements include adding raised intersections with bulb outs, lighting, street furniture, streetscape, bike racks, signage, wayfinding and street conversions.
