When complete, passengers will be able to ride nearly 40 miles of fast, safe, reliable light-rail service. This extension will better connect key points of the Seattle community, including from Eastside to downtown Seattle and Seattle-Tacoma International Airport.

The HNTB-led joint venture provided final design services for the Bellevue to Redmond portion and is currently providing construction design services and developing additional design packages for the entire project. Project scope includes approximately seven miles of double-track light-rail guideway, eight stations, the SEM tunnel in downtown Bellevue, and long-span bridge crossings over Interstates 405 and 90.
