Both are slightly shorter than the Evergreen Point Floating Bridge at 5230 meters each, yet together they form a impressive network over Lake Washington.

Why the Evergreen Point Floating Bridge Matters

The Evergreen Point Floating Bridge stands out due to its extensive length and width. Its strategic positioning and design make it a vital transportation link in the Seattle area, connecting the bustling city with its more suburban regions. The bridge's impressive engineering has been recognized, making it a symbol of modern construction and innovation.

Understanding the Importance of Floating Bridges

Floating bridges are essential structures for crossing large bodies of water, especially where piers or other traditional bridge foundations might be impractical or prohibitively expensive. They consist of pontoons that float, supported by buoyancy, and large concrete slabs that span between them to support vehicle traffic.
