NW Market St is an east-west arterial and considered a major truck street in Seattle's freight network. This 4-lane street is a critical piece of Seattle's arterial network  in need of repair. We will be doing a full concrete reconstruction, which will support continued growth in the area, including multiple frequent transit routes and freight. This work also contributes to our levy goal to pave up to 180 lane-miles of arterial streets by 2024.

The scope of this project includes:

  • Full concrete reconstruction of NW Market St between 24th Ave NW and 15th Ave NW (excluding intersections at 24th Ave NW and 15th Ave NW)
  • Curb ramp upgrades and replacements
  • Sidewalk repair
  • Tree pit expansion
  • Water main upgrades
  • Stormwater drainage improvements
  • Minimal parking removal

We will continue to evaluate opportunities for transit improvements in partnership with the upcoming Route 44 Transit-Plus Multimodal Corridor Project.

Outreach is conducted throughout the planning, design, and construction phases and we encourage you to attend public meetings and engage with us online.

The Three Stages of a Project

Project timeline

1. Planning
    What we do: Collect traffic data, review plans and gather community experiences to define options.

2. Design
    What we do: We work with the community and produce a more detailed project design.

3. Construction
    What we do: We construct the project and keep the community informed on the latest construction updates, schedule, and expected impacts.


This project is part of SDOT's Arterial and Asphalt and Concrete (AAC) Paving Program. Design and construction of our paving projects, as well as the safety and mobility improvements shown, are funded by the Levy to Move Seattle, approved by Seattle voters in November 2015. We also seek additional funding through grants, when available. Learn more about the levy at seattle.gov/LevytoMoveSeattle.
