I-225 Rail - R Line
Current construction list and detour maps
The I-225 Rail Line is a 10.5-mile light rail line within the city of Aurora that will provide key regional connections to the East and Southeast rail lines. It is part of FasTracks, RTD's voter-approved plan passed in November 2004 to expand transit service across the Denver metro region.
It will provide connectivity to major activity centers like the Aurora City Center, Anschutz/Fitzsimons Medical Center and Denver International Airport through a transfer at Peoria to the East Rail Line.
