Southbound I-405 between Coal Creek Parkway in Bellevue and North 30th Street in Renton will be closed from 11:30 p.m. to 4 a.m. nightly, from Wednesday, May 13 to the morning of Friday, May 15.
Project overview
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 and safety improvements to offer more reliable travel choices and keep drivers, transit riders and freight moving.
The Renton to Bellevue project will add new capacity to create a two-lane ETL system between SR 167 in Renton and Northeast Sixth Street in Bellevue. In general, the project will add one new lane in each direction and combine the existing HOV lane with the new lane to create a dual ETL system.
The new ETLs 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 ETL system. This project is designed to improve speeds and trip reliability for all travelers and support the new I-405 Bus Rapid Transit (BRT) line between Lynnwood and Tukwila included in the voter-approved Sound Transit 3 package.
What to expect
