East Link Project Supplemental Draft Environmental Impact Statement (SDEIS)

East Link is a voter-approved regional transportation project that is part of a comprehensive long-term expansion of mass transit in the region. Once completed, East Link will connect the Eastside's biggest population and employment centers with stations serving Seattle, Mercer Island, Bellevue, Bel-Red and Overlake in Redmond. By 2030, East Link will serve about 50,000 daily riders on one of the regions' most congested travel corridors.
