Project Overview

Rainier Ave S has played an important role in moving people and goods throughout the region. Renton has experienced rapid growth in the previous decades, outpacing all other major populated metros in the state. To accommodate, the City of Renton has completed several multimodal projects along Rainier Ave S to improve traffic operations, reduce collisions, and provide greater ease of non-motorized and transit-based travel.

The city is currently constructing Phase 4 of the Rainier Ave S Improvements. Phase 4 improvements will create a safer, more accessible, and vibrant pedestrian environment and improve overall traffic flow through the corridor.

The project will include the following elements:

  • Sidewalk widening with streetscaping
  • Pedestrian-scale lighting
  • Pedestrian activated traffic signal
  • Upgrading existing traffic signals
  • Transit improvements, including an extended Business Access and Transit lane (BAT lane)
  • Planted buffer strips and landscaped medians

Phase 4 of the Rainier Ave S Improvements will extend from S 3rd St to NW 3rd Pl. A pedestrian and bike path will also be built on the east side of Rainier Ave N, between Airport Way and NW 3rd Pl.

Project Status

In December 2022, Renton City Council awarded the construction contract to Pivetta Brothers Construction Co. Construction is anticipated to begin in Spring 2023. Initial work includes tree trimming and removal, surveying activities, and installing new utilities in a shared joint utility trench in the right of way.

Community Outreach

Prior to the start of construction, the project team will reach out to the community to share information on the project, discuss upcoming construction activities, and gather information from frontline stakeholders. This will help anticipate needs and minimize construction impacts on the community.

There will be virtual and in-person engagement activities available to stay up to date on the construction progress and project timeline.
