S Henderson Stairway
Updated: June 22, 2022
What's Happening Now?
Construction has started!
We are excited to announce that construction has started on the new Henderson Stairway. Construction is expected to last four to five months.
Recent and upcoming construction activities
1. Looking east from the project site after clearing and prepping the work area.
2. Initial grading of the work site in preparation for pile foundation work.
3. Grading and preparing the intermediate stairway landings for the pile foundation work.
Crews have been clearing and grading the project area in preparation for the upcoming work, including:
- The stairway will have pile foundations, which is a series of columns constructructed into the ground. The piles transfer weight from the stairway structure to deeper soil with high weight-bearing capacity.
- Crews will do everything possible to complete this work as quickly, quietly, and safely as possible.
- Stairway form work
- In the next couple of weeks, crews will begin form work for the stairway, starting at the top of the site at 39th Ave S.

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.
