View of the SR 520 floating bridge on a sunny February day, looking west. Construction barges are also visible in the background, which crews are using to build the new SR 520 West Connection Bridge. 

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 program area begins at I-5 in Seattle and extends to SR 202 in Redmond.
