The SR 520 Floating Bridge is a vital transportation link in Washington State, connecting Seattle to Medina across Lake Washington. Opened in 1963, it is the longest floating bridge in the world, measuring about 7,580 feet. The bridge consists of a series of pontoons that float on the lake's surface, allowing it to adapt to changing water levels. In 2016, a new bridge was completed to replace the original structure, enhancing safety and capacity. The SR 520 corridor is crucial for commuters and travelers, providing access to various neighborhoods and reducing traffic congestion in the region.
