23rd Avenue Corridor Improvements Project

February 2, 2018

 We completed the first phase of the project, from E Madison St to S Jackson St, in 2017. Construction of the second phase, from S Jackson St to Rainier Ave S, is anticipated to start as soon as April 2018 and last approximately one year. Planned improvements include sidewalk improvements, repaving the street, a new three-lane configuration from S Jackson St to S Holgate St, replacing the water main under the street from S Jackson St to S Norman St, and more.


There will be a long-term construction detour on 23rd Ave S. Southbound 23rd Ave S between S Jackson St and S Norman St. Traffic will be detoured to Martin Luther King Jr Way S while crews replace the water main and rebuild the street. Northbound travel will be maintained on 23rd Ave S, with traffic reduced to one lane. See the above map with the detour route for reference. We will be holding another public meeting before construction begins. Stay tuned for more details.
