Project phases - Downtown Redmond Link Extension

Downtown Redmond Link extension timeline

Environmental review and preliminary design

Planning and environmental review: 2006-2011

From 2006-2011 the guideway and stations between NE 40th Street (the future Redmond Technology Center Station) and downtown Redmond were part of the East Link Extension environmental review.

Environmental review and preliminary engineering for East Link Extension was completed in 2011. Sound Transit issued a Final Environmental Impact Statement (FEIS) and the Sound Transit Board selected the project to be built in July 2011. The Federally issued Record Of Decisions (ROD) finalized the alignment that the Sound Transit Board selected through this work, completing the required process under the National Environmental Policy Act.

While the environmental review was completed, an economic downturn starting in 2007 required the project to postpone design and construction of the final two stations until additional funding could be identified. Downtown Redmond Link Extension was approved by voters in 2016 as part of the Sound Transit 3 Plan.

Environmental refresh and preliminary engineering: 2017 - 2018

Sound Transit is refreshing the environmental documentation to reflect current conditions for the final two stations that are now funded through construction.
