S Henderson Stairway

Updated: March 6, 2023

What's Happening Now?

This month, crews will be back to work on the Henderson Stairway project. Crews will install the stairway railings, finish the landings at top and bottom of stairway, and other improvements. Some of this work will require a partial closure of 39th Ave S during construction hours. There will be a flagger present to help drivers navigate around the work zone. Help ensure everyone's safety by following project signs and instructions of crew members.

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.
