The SR-520 Floating Bridge Replacement and HOV Program was constructed by Kiewit Constructors, General Manson Constructors and Flatiron Steel Works Co. as a joint venture project.

It was built to enhance public safety and mobility by replacing the highway’s aging, vulnerable current SR-520 Bridge and making significant transit and roadway improvements throughout the East – West corridor.

The bridge runs between the communities of Medina/Bellevue across Lake Washington and into the Downtown Seattle core. The construction program’s planned improvements extend from I-5 in Seattle to I-405 in Bellevue.
