Seattle’s Sound Transit opened the Crosslake Connection, which carried passengers on light rail vehicles across a floating bridge for the first time.

The momentous achievement completes the Link 2 Line, uniting the Eastside with Seattle, the Seattle-Tacoma International Airport, Federal Way, Lynnwood, and communities in between.

The final seven-mile segment of the 2 Line includes new stations at Mercer Island and Judkins Park and connects to the 1 Line at the International District/Chinatown Station. The Link light rail system now spans 63 miles and includes 50 stations.

“The milestone we celebrate today is possible because of a shared vision that began more than 60 years ago and has continued through the decades with resolve, innovation, and hard work,” said Sound Transit CEO Dow Constantine. “We all share in this achievement — from the regional leaders who had the foresight to plan for future transit, to the voters who put their support behind those plans, to the thousands of people who have worked to bring the vision to life.”

The opening of the Crosslake Connection completes the expansion of the Link system approved by voters in 2008 as part of the Sound Transit 2 ballot initiative.

The 1 Line extension to Federal Way opened in December 2025, following the openings of the 2 Line to downtown Redmond in May 2025; the initial segment of the 2 Line on the Eastside in April 2024; and the 1 Line extension to Lynnwood in August 2024.

Service on both the 1 Line and 2 Line will run from about 5 a.m. to 12 a.m. seven days a week. Trains will run approximately every eight minutes at peak at the new stations, and between 10 and 15 minutes the rest of the day. Between Lynnwood City Center and International District/Chinatown stations, combined 1- and 2-Line headways will mean trains arrive every four to five minutes.

 ST Express buses will operate on existing routes and schedules until August 2026.
