Why is WSDOT improving I-405 from Renton to Bellevue?
Travelers on Interstate 405 between Renton and Bellevue experience one of the state’s worst commutes. The I-405 Renton to Bellevue Widening and Express Toll Lanes project includes multimodal transportation improvements to offer more reliable travel choices and keep drivers, transit riders and freight moving.
The End Result
The Renton to Bellevue project is designed to reduce congestion and improve safety performance along one of the state’s most congested sections of highway.
The project will add new capacity to create a two-lane express toll lane system between SR 167 in Renton and Northeast 6th Street in Bellevue. In general, the project will add one new lane in each direction. The existing HOV lane will be combined with this new lane to create a dual express toll lane system.
The new express toll lanes will connect to the existing express toll lane system between Bellevue and Lynnwood, as well as the SR 167 HOT lanes via the I-405/SR 167 Interchange Direct Connector, to create a 40-mile system of express toll lanes. This project is designed to improve speeds and trip reliability for all travelers and support the new I-405 Bus Rapid Transit line between Lynnwood and Tukwila included in the voter-approved Sound Transit 3 package.
