RapidRide I Line is coming to Auburn, Kent and Renton
King County Metro is preparing to build 17-miles of new RapidRide service in Kent, Renton, and Auburn. Construction will begin in Fall 2025. Once the RapidRide I Line is in service in 2027 it will provide connections to the Renton Transit Center, Kent Transit Center and Auburn Station. The I Line will also connect riders to the RapidRide F Line, Sound Transit buses; Sounder Train; and local bus service, making it easier for people to travel to and from regional destinations and access a network of local bus routes. Metro is building RapidRide I Line to meet a critical need for improved north-south transportation options in south King County.

Take our online survey!
Construction may cause temporary changes or disruptions to your usual access or travel patterns along the RapidRide I Line route. The contractor will work in designated construction zones with potential temporary local impacts over the course of the project. To help us prepare for construction please take our survey by August 18. This will help Metro understand how residents, visitors, and business owners get around the project route.
