The City seeks to promote, manage, and maintain a safe, efficient, and integrated multi-modal transportation system to support a healthy and vibrant community. This project aims to create an interconnected multimodal network, completing a link in the Bridge-to-Bridge trail between Manette Bridge and Evergreen Park, while also improving safety for all users.
The City’s downtown growth center is poised to experience substantial growth in the very near future given the developments both under construction and currently being permitted. Traffic studies completed by the City show that the evening peak hour traffic through the existing signalized intersection at the west end of the Manette Bridge backs up over 1/3 mile south on Washington Avenue, affecting all side streets and create gridlock in the downtown area. A roundabout is both an immediate and long-term solution to the congestion and delay.
North of this intersection, the existing corridor along 11th Street up to Pacific Avenue has limited pedestrian facilities. The existing sidewalks are discontinuous and in a state of disrepair, with obstructions reducing the available Pedestrian Access route (PAR) width and ADA accessibility. Bike users have to share the lane with vehicles as there are also no existing bike lanes within this section of roadway. In addition, sidewalk and street pavement on the local (lower) Washington Avenue will be reconstructed to improve paving, parking, and ADA accessibility to 11th Street Place.
With the roundabout, traffic capacity will be improved with a reduction in delays. The pavement will be reconstructed, and dedicated bike lanes will be added. Pedestrians will benefit from wider sidewalks and improvements to curb ramps. The project will include improved lighting for pedestrians and vehicles that use the corridor as well as waterline and storm drainage improvements. The project will greatly enhance safety and will have a profound impact on increasing pedestrian and bicycle activity.
The City has been offered a Surface Transportation Program (STP) grant through the Puget Sound Regional Council (PSRC) and a Transportation Improvement Board (TIB) grant to design and construct a roundabout at the west end of the Manette Bridge where it intersects with Washington Avenue. The grants also funds the full street reconstruction of Washington Avenue/11th Street between the new roundabout and Pacific Avenue along with street, parking, and sidewalk/pedestrian improvements along Washington Avenue up to 11th Street Place. The proposed improvements will also include providing ADA accessible sidewalks, bike lanes, lighting, replacing the aging water mains at Pleasant Avenue and Highland Avenue, and stormwater improvements.

Total Estimated Cost
Engineering design is anticipated to be completed in late 2022. Comments received during the prior public outreach meetings have been incorporated into the design where possible. Advertisement for construction is estimated to occur in February 2023 with construction beginning as soon as April 2023. Construction of the project is planned to occur in two phases as follows:
|PHASE 1||Pacific Avenue to North of Proposed Roundabout|
Thru traffic on 11th St and Washington Ave in this phase will be restricted to local traffic only where necessary. Detour route(s) will be provided.
|PHASE 2||West Manette Bridge Intersection with Washington Ave (Roundabout Construction)|
Intermittent closures of the intersection and Manette Bridge traffic are anticipated to complete construction of the roundabout. Detour route(s) will be provided.
Note: Phasing and durations shown are anticipated, but subject to change during construction.
