The Washington State Department of Transportation has released artist's renderings of what the new $4.65 billion State Route 520 Bridge will look like. The renderings depict a six-lane structure that incorporates a 14-foot-wide bike and pedestrian path. Concrete pontoons for the bridge are scheduled to be delivered by barge in late summer. "Starting floating bridge construction on Lake Washington is a huge milestone 15 years in the making," said state Transportation Secretary Paula Hammond. "Crews will build a stronger, more reliable floating bridge -- and designs show the integrated architectural features will be distinctive and memorable for generations to come."
