I-90 Two-Way Transit Project

The I-90 Two-Way Transit & HOV Operations project will improve regional mobility by providing safe and reliable two-way transit on I-90 between Bellevue and Seattle. The WSDOT and Sound Transit project will provide full-time HOV lanes for eastbound and westbound traffic on the outer I-90 roadways and new direct-access ramps for transit and HOVs on Mercer Island and in Bellevue. This collaborative project will prepare the center roadway for the East Link Extension.

The project is being implemented in stages due to timing and availability of funding.
