East Link Final EIS documents

East Link is Sound Transit's voter-approved project to expand light rail from downtown Seattle to the Eastside with stations serving Mercer Island, south Bellevue, downtown Bellevue, Bel-Red, and Redmond's Overlake area. East Link will connect to the Link light rail system between downtown Seattle and Sea-Tac Airport. Sound Transit is also conducting environmental review on a future extension to downtown Redmond.

Federal Transit Administration Record of Decision

The Record of Decision (ROD) culminates over five years of environmental review that Sound Transit undertook in cooperation with community members and local and regional governments. Sound Transit received more than 1,800 comments during the environmental review and held 28 open houses, hearings and workshops to gather community input. The ROD finalizes the alignment that the Sound Transit Board selected through this work, completing the required process under the National Environmental Policy Act.
