Greenwood Ave N

Updated: January 2, 2020

What’s happening now?

Construction is underway on the west side of Greenwood Ave N. Since work began in September, we have installed utility lines that will be able to accommodate the storm water runoff that will come with the new curb and gutter. 

Now, we are beginning to install sidewalks, starting with the curb and gutter between N 140th and 143rd streets. As part of this work, we will pour concrete near driveways of residences and businesses. During this work and while the concrete sets, driveway access may be temporarily unavailable.  If you are impacted you will receive advance notification.

As we get ready to build new sidewalks in early 2020 on Greenwood Ave N, our crews will need plenty of space to work safely. We plan to keep the current roadway configuration, with one lane in each direction, in place until the project is complete in spring 2020. Until then, we ask that drivers be cautious when traveling through the work zone - we appreciate your patience during construction as we work to make these safety improvements!

Project Overview

We are working to repave Greenwood Ave N between N 137th and N 145th streets, as well as adding sidewalks, curbs, and parking strips where they don't presently exist. Other improvements will include Americans with Disabilities Act-compliant curb ramps at each intersection in the project area, pedestrian signal improvements at N 145th St, and a new traffic signal at N 137th St. These improvements will help achieve Seattle's Vision Zero goal to end all traffic deaths and serious injuries by 2030.

The first phase of the project was completed in 2018 and installed a new sidewalk, planting strip, curb, and gutter on the east side of Greenwood Ave N. Crews also installed a new pedestrian-activated traffic signal at N 137th St. 

The second phase of the project, currently underway, will construct a new sidewalk, planting strip, curb and gutter on the west side of Greenwood Ave N between N 136th and N 145th streets. After the sidewalk work is complete, crews will return in spring 2020 to pave the entire roadway on Greenwood.
