World’s First Light Rail on a Floating Bridge Opens in Seattle | Crosslake 2 Line Explained

Seattle is about to make transportation history. The Crosslake Connection — part of Sound Transit’s 2 Line expansion — will become the world’s first light rail system to operate on a floating bridge. Beginning March 28, 2026, trains will run across Lake Washington on the Homer M. Hadley Memorial Bridge, a massive concrete pontoon structure that literally floats on the water. Unlike traditional rail bridges built on fixed piers, this structure rises and falls with waves, wind, and changing water levels. Engineers had to design specialized expansion joints and flexible track systems to ensure trains remain aligned while the bridge moves. In this episode, we break down: • How floating bridges work • How rail can safely operate on moving structures • Why this is a major milestone for urban transit • What the Crosslake 2 Line means for Seattle, Bellevue, and the region This is not just a transit upgrade — it’s a first-of-its-kind engineering achievement.
