Pedestrian Safety Improvements:  23rd Avenue S / S Walker Street

Last Updated: January 28, 2015

Construction Update

On Monday, January 12, SDOT will begin construction of pedestrian improvements on the west side of Rainier Avenue S, between 23rd Avenue S and at S College Street. To reduce construction duration and impacts, crews will work in the daytime, from 7:00 AM to 3:00 PM, as well as at night, from 8:00 PM to 7:00 AM. This work is anticipated to take approximately two weeks to complete, during which you can expect temporary driveway and parking restrictions, lane restrictions on Rainier Avenue S, pedestrian detours and impacts to transit stops. As soon as Monday, January 26, construction along S College Street and 23rd Avenue S will begin, during which more traffic restrictions will be in place. This will include driveway restrictions (up to 7 days), lane and parking restrictions on S College Street and 23rd Avenue S. Improvements in this area will include the installation of new curb ramps and segments of sidewalk.This work is anticipated to be complete by mid-April.

During construction you can expect:

  • Lane restrictions on Rainier Avenue S, S College Street and 23rd Avenue S
  • Temporary driveway closures of up to 7 days, advance notice will be provided
  • Parking restrictions near the work area
  • Daytime and nighttime construction activity
  • Noise, dust and vibration associated with concrete removal and paving
  • Parking restrictions
  • Impacts to bus stops

The project team will work with the community to keep residents, businesses and travelers informed of detour routes and construction impacts as the information becomes available. Construction information will also be made available on this webpage and distributed through the project email list.

Project Description

The Seattle Department of Transportation is working to make streets in North Beacon Hill safer and more comfortable for everyone. As part of that effort, SDOT is planning to construct pedestrian transportation safety improvements in 2014 and 2015 along 23rd Avenue S from S Waite to S College streets, as well as along two block of S College and up at S Walker Street.

Many of these improvements were recommended in community plans including the Southeast Transportation Study (SETS). Most importantly, these types of pedestrian facilities improve safety for all roadway users. Projects include:

  • New sidewalk on the east side of 23rd Ave S from S College St to S Waite St
  • New sidewalk on the south side of S College St from 23rd Ave S to Rainier Ave S
  • Curb bulbs at Rainier Ave S and S Walker St to improve visibility and safety
  • Curb ramps at 23rd Ave S and S Walker St
  • Curb ramps at MLK Jr Way S and S Walker St

One final component is a new open space for the community to enjoy, on the east side of 23rd Avenue S, at, and just north of, S Bayview Street. The space may have landscaping, grass and native flowers, etc., based on what the surrounding community envisions.

Project Benefits

The goal of these pedestrian safety improvements is to help make North Beacon Hill safer and more comfortable for multiple travel modes. The work includes:

  • Sidewalk along a route to and from a school bus stop
  • ADA compliant curb ramps, for smoother better access
  • Curb bulbs to improve pedestrian crossings
  • Community open space

Environmental Review

After a careful environmental review, the Seattle Department of Transportation (SDOT) has determined that the pedestrian projects in the 23rd Ave S/S Walker St area will not have a probable significant adverse impact on the environment. SDOT is required to consider the environmental consequences of proposed projects under the Washington State Environmental Policy Act (SEPA). SDOT issued a Determination of Non-Significance (DNS) on Tuesday, February 18, 2014. The SEPA checklist, linked below, includes a summary of the project’s impacts on water quality, air quality, plants, animals, hazardous materials, noise, land use, light, recreation, cultural resources, parking, and other disciplines. The public comment and appeal periods have closed.

This work is funded by the nine-year voter approved Bridging the Gap Levy, Safe Routes to School, Sidewalk Development Program, and Washington State Transportation Improvement Board.


These improvements reached 100 percent design in April 2014. The project went to construction in October 2014 and the project team anticipates the work will be completed in early 2015.
