SR 520 Bridge Replacement and HOV Program


Buses and carpools now enjoy their own lane on SR 520’s reconstructed corridor between Lake Washington and I-405. The new SR 520 floating bridge will have HOV lanes when it opens to traffic a year from now, and in 2017, the highway’s HOV lanes will extend to Montlake Boulevard in Seattle.
