Open for operations (2032*)
*Sound Transit is working toward an opening in 2032 but is also pursuing measures to advance the opening earlier (potentially 2030). If the Midway Landfill alternative is selected as the project to be built, the opening date would be between 2035 and 2037 depending on the subsurface construction design option. We will share an updated project schedule when we have more certainty.
