The state Department of Transportation and Sound Transit plan to add high-occupany vehicle lanes to Interstate 90 between Seattle and Bellevue. WSDOT will also build new HOV on- and off-ramps on Mercer Island and will improve I-90 HOV access at Bellevue Way.
I-90 has a two-lane reversible center roadway between Seattle and Bellevue for buses, carpools and vanpools only. Those HOV lanes are open to westbound traffic in the mornings and eastbound traffic in the evenings. However, buses, carpools and vanpools traveling in the opposite direction are forced to use often crowded general-purpose lanes.
WSDOT and Sound Transit will add outer HOV lanes in each direction. The center roadway will be set aside for light rail.
- In October 2006 contractors were solicited for the first stage of the project, and they are expected to begin work in April 2007.
- In May 2004, WSDOT, Sound Transit and the Federal Highway Administration issued the final environmental impact statement for the project. The EIS is available for viewing and downloading from the Sound Transit website.
