S Henderson Stairway

Updated: August 5, 2022

What's Happening Now?

Construction is well underway for the new Henderson Stairway. Construction is expected to last four to five months.

Recent and upcoming construction activities

Crews set the first stairway concrete forms this week. The bike runnel was poured along with five light pole foundations.

    Starting the week of August 8th, there will be weekly concrete pours on Thursdays. A line pump will be staged on 39th Ave S for distribution of the concrete. One travel lane will be maintained for vehicle access on 39th Ave S.

    Once the top half of the stairway is done, the line pump will be staged on 41st Ave S to complete the remaining concrete pours.

    Project Background

    Beginning in 2018, we began the feasibility and planning process for a new stairway on S Henderson St between 39th Ave S and 41st Ave S (approx. 440 ft). The Henderson Stairway will better connect south Beacon Hill residents to the Rainier Beach light rail station, local schools and community amenities, while helping to advance the City's Pedestrian Master Plan goals.

    This stairway is currently planned to include multiple landings to meet ADA requirements, lighting, and a runnel for people to walk their bikes up the stairway. The planned stairway, which has received several community requests, provides a direction connection to Rainier Beach Station from South Beacon Hill and reduces walking distance by approximately 0.5 miles.
