Introducing the MLK Jr. Way S Corridor Signal Synchronization Pilot

The Seattle Department of Transportation (SDOT) and Sound Transit (ST) are conducting a study to test a method to synchronize signal lights and light rail timings along Martin Luther King (MLK) Jr. Way S. If successful, this will boost efficiency and safety for all travelers while keeping light rail trains on time. The pilot will be conducted in three phases.

Phase one will begin in the early morning on Sunday, March 3, 2024 (before regular light rail service). Phases two and three will depend on the data collected before and after implementation to evaluate the impact and make future adjustments. Learn more about the pilot program.


We’re working on improving safety and transit service and making it easier to walk, bike, and take transit throughout Southeast Seattle, including Beacon Hill and the Rainier Valley.

Projects are in construction, nearing final design, or have just begun. No matter what stage they're in, we want to hear from you.
