Something extraordinary happened on Lake Washington in September 2025. Under the cover of night, steel met water in a way never before seen anywhere in the world: an electric train glided across a floating bridge under its own power. This wasn’t just a test – it was a bold demonstration of innovation, determination, and decades of engineering expertise. The historic crossing not only marked a world-first achievement, but also signaled the dawn of a new era in public transportation, one that will soon unite Seattle, Bellevue, and Redmond with faster, cleaner, and more reliable connections.
Gateway to Regional Connections
The successful bridge crossing unlocks the final piece of Sound Transit’s East Link Extension, soon to be known as the 2 Line. When passenger service begins in early 2026, commuters will enjoy a 30-minute ride between downtown Seattle and downtown Bellevue – regardless of highway traffic conditions.
This achievement represents more than just a transportation breakthrough. It symbolizes the region’s commitment to sustainable transit solutions that connect communities while reducing carbon emissions.
Despite facing multiple delays throughout its development, the project’s completion will transform how people move throughout the Puget Sound region. The floating bridge segment creates a vital link in what will eventually become a 116-mile regional light rail network…
