Lynnwood Link extension

The Lynnwood Link extension is a planned Link light rail extension traveling north from Northgate to Lynnwood in Snohomish County, Washington, United States. The 8.5 mi light rail extension includes stations in Lynnwood, Mountlake Terrace, and Shoreline along Interstate 5. It will be served by the 1 Line when it opens on August 30, 2024, and the 2 Line in 2025. The project was funded by the Sound Transit 2 (ST2) package approved by voters in November 2008, and began construction in 2019. Ridership is expected to be 63,000 to 74,000 daily in 2035.

Route and stations


In April 2015, the final environmental impact statement (EIS) for the extension was released, and a Record of Decision from the Federal Transit Administration was received in July 2015. The Lynnwood Link Extension begins at Northgate station in Seattle and follows Interstate 5 with stations at Northeast 145th Street, Northeast 185th Street, Mountlake Terrace Transit Center, and Lynnwood Transit Center. The EIS also included accommodations for infill stations at NE 130th St and 220th St SW.

History
In August 2017, Sound Transit announced that the project would be delayed six months (from late 2023 to mid 2024) and would cost $500 million more than expected, bringing the final budget to $2.9 billion. The changes were due to rising costs associated with land acquisition, labor, and materials in the local market.

The project's groundbreaking ceremony was held on September 3, 2019, and included Governor Jay Inslee, U.S. Senators Patty Murray and Maria Cantwell, and U.S. Representatives Rick Larsen and Suzan DelBene. Testing of trains on the extension began in January 2024 and progressed in June to pre-revenue service with simulated schedules.

Service on the 1 Line to Lynnwood is scheduled to begin on August 30, 2024. Construction delays on the 2 Line will limit the number of available trains to Lynnwood until 2025. Major changes to the bus network in Shoreline and Snohomish County, including the truncation of most commuter buses, are scheduled for September 14, 2024. Some Sound Transit Express buses will continue to connect Snohomish County to Downtown Seattle during peak hours to provide additional capacity until the 2 Line is extended in 2025. An infill station at Northeast 130th Street in Seattle was funded by the Sound Transit 3 package and is scheduled to open in 2026.
