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.

Businesses along S 3rd Street along the construction area can be accessed via S 4th Street. Our goal is to maintain a consistent detour route for the duration of the road closures on S 3rd Street. Refer to the route below highlighted in yellow to navigate the downtown as work on S 3rd street continues.

Detour Route

S 3rd St Detour Route

Noted street closures are daytime closures during construction hours. A minimum of one lane will be open on S 3rd Street after construction hours. Please follow posted signs and directions from flaggers for safe access.


Parking Sign

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

The City Center Parking Garage offers up to 10-hours of free parking. A monthly permit for the City Center Parking Garage can also be purchased for $35.

There are several public parking lots downtown that offer up to 2 hours of free parking and convenient access to downtown businesses. For more information about places to park downtown, please check out the City’s Downtown Parking Map.

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.

Current Work Areas


1. Stormwater Utility Work on Shattuck Ave S

DUIP completed utility work south of S 3rd St on Shattuck Ave S. We are working on final steps to completing work north of S 3rd St towards S 2nd St. Through traffic on Shattuck Ave S will continue to be reduced to one lane both directions. Please follow posted signs and directions from flaggers for safe access.

2. Sewer Utility Work on S 3rd St

DUIP continues installation of the sewer main between Burnett Ave S and Logan Ave S. During construction work hours, S 3rd St will be closed between Burnett Ave S and Logan Ave S and reduced to one lane between Logan Ave S and Shattuck. A detour to S 4th St via Shattuck Ave S and Burnett Ave S is in place to route traffic around this construction. Signage for local and business access will be in place along the detour route. During non-work hours, S 3rd St will maintain a minimum of one lane of traffic throughout the project area (Burnett Ave S to Rainier Ave S). Work will continue moving west, block-by-block, towards Rainier Ave S. Road Closures on S 3rd Street will move west with the construction efforts.

3. Storm Utility work on S 3rd St

Storm utility work on S 3rd St east of Rainier Ave S and west of Shattuck Ave S is near completion and all lanes of S 3rd Street are open between Rainier Ave S and Shattuck Ave S. S 3rd Street is reduced to one lane beyond Shattuck Ave S for sewer main construction currently occurring between Burnett Ave S and Logan Ave S. Local and business access on S 3rd St will be maintained. A detour is in place routing traffic to S 4th Street.

  • We know there will be impacts, but we will do everything we can to maintain access

Traffic Management

  • Where possible, a minimum of 1-lane of traffic will be open to traffic at all times
  • During construction hours, detours will be established when traffic cannot safely proceed through the work zones

  • Additional lanes may be open after construction hours when possible and safe.

  • Detour and traffic signs will signal vehicle reroutes and access

Road Closures

  • Block by block sections of S. 3rd Street will be closed to vehicle access during the working day
  • Closure of each section is expected to last approximately 2-4 weeks
  • For safety reasons, roads will be closed in areas where deep trenching will occur

  • Closure of roads will be coordinated with the Wells – Williams Project, where applicable

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.
