Learn about the science behind floating bridges from WIRED.
Washington’s love of floating bridges can be traced to the topography around Seattle. Lake Washington, east of the city, plunges to a depth of more than 200 feet, and the bottom is, from an engineering perspective, crap. It’s soft silt, which makes building a conventional suspension bridge with rooted towers quite difficult (read: expensive). Each tower would have to be about 630 feet tall, the state DOT says—twice the height of the sentinels holding up the Brooklyn Bridge.
