SR 520 Eastside project overview

The Eastside Transit and HOV project will widen SR 520 to six lanes from Medina to Bellevue. The project includes rebuilding interchanges, building highway lids and transit stops in the center of the highway and installing fish-passable culverts.

WSDOT awarded the $306 million design-build contract to Eastside Corridor Constructors, a joint venture of Granite Construction Company and PCL Construction Services. SR 520 highway construction continues through December 2013.
