Extending mass transit from Northgate to Lynnwood

Sound Transit is preparing to extend mass transit from Northgate to Lynnwood, which voters approved as part of the Sound Transit 2 Plan in 2008, along with funding to continue planning future service all the way to Everett. The North Corridor Transit Project will connect to and build on the Link light rail line that opened for service between downtown Seattle and Sea-Tac Airport in 2009. Construction is currently underway on a light rail extension to the University of Washington scheduled to open in 2016, followed by service to Northgate targeted in 2021. Voter-approved additions over the next few years will bring 36 new miles of service to the north, south and east, creating a 55-mile light rail system serving the region.

Alternatives Analysis

The North Corridor Transit Project relies on receiving federal assistance to complete the project. In order to qualify for federal grants, Sound Transit completed an Alternatives Analysis (AA) - available here. The AA required examination of reasonable alternatives to meet the needs of the corridor and will help Sound Transit identify a preferred transit mode and route.

Federal funding is key to keeping this project affordable, and is especially important as Sound Transit responds to impacts of the current economic recession that have reduced projected revenues by about 25 percent through 2023 and have created schedule risks for this project.

Project benefits

8-9 miles of new mass transit service
Northgate to Lynnwood with several new transit stations
Frequent, reliable service between south Snohomish County and the University of Washington, downtown Seattle and other regional destinations
Increased mobility, access and transportation capacity for residents and workers
Targeted to open for service to public in 2023
