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.
