Thank you for your interest in the Rainier Ave S Bus Lane Project to make transit an accessible, convenient, and reliable transportation choice for everyone living in, working in, and visiting the Rainier Valley. Please feel free to share this information with your fellow neighbors and encourage them to sign up to receive updates using this link.

Rainier Ave S Bus Lane Project Update

Construction of the Rainier Ave S Bus Lane Project began on September 3! Crews will work in segments along the project area through spring 2025.


Over the next two weeks, you will see the following construction activities near Rainier Ave S/S Grand St and Rainier Ave S/S Massachusetts St:

  • Crews will continue working on the corner of Rainier Ave S and S Massachusetts St through early April
    • During this construction, a single lane of both Rainier Ave S and S Massachusetts St will be closed to accommodate the work. Expect delays for the next week around that intersection.
  • Depending on the weather, crews will work overnight over the next few weeks to install striping along Rainier Ave S from S Walden St to S State St
    • During the striping work, one lane will remain open in each direction on Rainier Ave S

Weekend Work:

  • On Saturday, March 29, crews will continue installing the new traffic signal at Rainier Ave S and S Grand St. The outside lanes will be closed in each direction during this work.
    • The signal lights will be turned on at a later date

What to expect during construction

Typical work hours are Monday - Friday, from 7:00 AM to 4:00 PM. During this time you can expect:

  • Temporary traffic revisions to accommodate construction vehicles and equipment
  • Temporary parking restrictions near work zones
  • Noisy construction activities, such as vehicle backup alarms for safety, heavy truck use, and the use of power tools.

Project Background

This project includes the extension of the northbound bus lane on Rainier Ave S from S Walden St to S State St, along with other safety changes requested by community members to make it easier and safer to get around on this busy street. This project will improve the reliability of the Route 7 bus and get us ready for the future RapidRide R Line.

Through collaboration with King County Metro, our goal is to make transit an accessible, convenient, and reliable transportation choice. This project includes:

  • New red painted bus lane between S Walden St and S State St in the northbound direction
  • Sidewalk repair in areas where the most people walk and take the bus on Rainier Ave S
  • At S College St and S State St:
    • New signals to make it easier and safer for people to cross the street
    • New marked crosswalks
    • ADA-compliant curb ramps
    • New Streetlights

We've been reaching out to community members, community-based organizations, and businesses in the project area and will continue to do so in the next few weeks. We want to share construction information with neighbors and community members.
