On March 28, 2026, the Puget Sound region reached a transformative milestone with the opening of the Crosslake Connection. This final seven-mile segment of the Link 2 Line marks a world-first engineering feat, carrying light rail vehicles across a floating bridge to finally unite the Eastside with Seattle and the broader regional transit network. With the addition of new stations at Mercer Island and Judkins Park, the Link system now spans 63 miles and 50 stations, completing the ambitious expansion plan approved by voters in 2008.

Sound Transit is currently in the midst of a transformative period, marked by the rapid expansion of its light rail network. Having successfully launched three major extensions—the Tacoma T Line expansion, the initial Eastside 2 Line, and the Lynnwood Link Extension—the focus now shifts to completing the remaining projects within the next two years. The forthcoming 2 Line extension to Downtown Redmond is poised to open in Spring 2024, with crews finalizing station construction, installing public art, and conducting crucial live wire and pre-revenue testing. This extension will add two new stations, enhancing connectivity within the Eastside.
