The SR 520 program launches summer public tours

This summer, the SR 520 Program is pleased to offer free public tours of construction along the SR 520 corridor. Tours of the new floating bridge will begin in May and will access the construction site from Evergreen Point Road in Medina. Separate tours of the West Approach Bridge North will begin in June and will take place in Seattle.


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.
