The stairway is being reconstructed at NE 90th Street and Ravenna Ave NE, starting this week. From SDOT:
SEATTLE—Seattle Department of Transportation’s Roadway Structures crews will construct a new staircase beginning Monday, February 27, and expect to complete the work before the end of April. The stairway will be closed starting Monday, 24 hours a day, seven days a week until completion. A map of the pedestrian detour will be posted at the top and bottom of the stairway.
The crews will demolish the old staircase, install form work, and then pour concrete for the new stairs and walkway.
The stairway was built in 1940 and does not meet current standards. This project is part of SDOT’s program to upgrade the 507 stairways that SDOT owns and is responsible for maintaining. The funding is provided by the Bridging the Gap transportation initiative.
