Massive concrete pontoons for the new SR 520 floating bridge now stretch more than a quarter mile into Lake Washington from the bridge’s easternmost pontoon, shown here in the foreground.
Building a new and improved SR 520 corridor
The SR 520 Bridge Replacement and HOV Program will enhance safety by replacing the aging floating bridge and keep the region moving with vital transit and roadway improvements throughout the corridor.
The 12.8-mile highway begins at I-5 in Seattle and extends to SR 202 in Redmond.
