The I-405/Renton to Bellevue Widening and Express Toll Lanes Project has an expected completion date of 2027. 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. The project is designed to improve speeds and trip reliability and support the new I-405 Bus Rapid Transit (BRT) line between Lynnwood and Tukwila.
