Link 1 Line Extension

This is the fifth light rail extension in the past three years for Sound Transit. Those include the T Line service to Hilltop, the 2 Line between South Bellevue and Redmond Technology stations, the Lynnwood extension into Snohomish County, and the 2 Line extension to Downtown Redmond. The Crosslake Connection, spanning the 2 Line across Lake Washington into Seattle, is expected in 2026.

Voters approved the Federal Way extension in 2008 as part of the Sound Transit 2 ballot measure. The project broke ground in the summer of 2020.

“Our team and community partners demonstrated remarkable resilience in overcoming the challenges of the Great Recession and the COVID-19 pandemic during the life of this project, while still finishing hundreds of millions of dollars under budget,” said Sound Transit CEO Dow Constantine. “This opening represents our ability to deliver for the residents of South King County and the region, connecting more people to opportunity via clean, frequent, reliable transit.”

Kiewit was the design-builder for the project, Funding for the $2.5 billion project includes a $790 million federal grant agreement from the Federal Transit Administration (FTA) and a $629.5 million low-interest loan from the U.S. Department of Transportation.
