The new SR 520 floating bridge won a prestigious national award in November as the country's top design engineering project of 2016. In addition, the Puget Sound Regional Council gave WSDOT a Vision 2040 Award this fall for completion of the new floating bridge. Read more about the highway project in this blog post by Transportation Secretary Roger Millar.

Program Overview

The SR 520 Bridge Replacement and HOV Program is enhancing public safety and mobility by replacing the highway's aging, vulnerable bridges and making significant transit and roadway improvements throughout the corridor. The construction program's planned improvements extend from I-5 in Seattle to I-405 in Bellevue.
