In summer 2015, the Washington State Legislature funded a portion of the I-405 Renton to Bellevue project. The project will add new capacity to create a two-lane express toll lane system between SR 167 in Renton and NE 6th Street in Bellevue.

Why is WSDOT improving I-405 from Renton to Bellevue?
Travelers on the stretch of I-405 between SR 167 in Renton and Northeast 6th Street in downtown Bellevue face one the most gridlocked routes in the state, particularly during peak travel times. The Renton to Bellevue Widening and Express Toll Lanes project will improve traffic flow and safety by continuing to build improvements from the I-405 Master Plan.

The Renton to Bellevue express toll lanes project was funded in the 2015 Connecting Washington transportation package. The project will add new capacity to create a two-lane express toll lane system between SR 167 in Renton and NE 6th Street in Bellevue.

The completed lanes will connect to the express toll lane system between Bellevue and Lynnwood, as well as the SR 167 HOT lanes.

The End Result
The Renton to Bellevue project will reduce congestion and improve safety along one of the state’s most congested sections of highway. This project will connect a 40-mile system of express toll lanes that improves speeds and trip reliability for all travelers.

Project Benefits

  • Congestion relief. The addition of the northbound and southbound lanes between SR 169 in Renton and NE 6th Street in Bellevue reduces congestion by increasing capacity. Express toll lanes help manage demand for limited road space by allowing non-carpools to pay a toll to use the HOV lanes for a faster, more reliable trip.
  • Safety. The additional capacity reduces the likelihood of sideswipe and congestion-related collisions.
  • Environment. WSDOT's I-405 Corridor Program team is designing the Renton to Bellevue widening and express toll lanes project to avoid and minimize impacts to the environment. Environmental improvements through this project will include new noise walls, stormwater enhancements, and fish culvert upgrades.

What is the project timeline?

  • Summer 2015: Funding obtained for preliminary engineering, right of way acquisition, and construction
  • 2019: Construction expected to start
  • 2024: Expected open to traffic
