RTD’s Downtown Rail Reconstruction Project will temporarily impact some light rail services

Alternate connections available for customers during construction

DENVER (Sept. 2, 2025) –– The Regional Transportation District (RTD) begins the next phase of light rail track reconstruction work today to replace aging rail infrastructure in downtown Denver and maintain the long-term integrity of its transit network. The agency continues to provide service to customers through alternate connections during construction.

Service changes took effect on Sunday, Aug. 31, along with modifications to light rail service due to the project work near the intersection of Kalamath Street and Colfax Avenue. The following options are available to customers to minimize disruption to their commute:

• All D Line trains have been rerouted to Denver Union Station, and customers can easily connect to the Downtown Loop using the 16th Street FreeRide or Free MetroRide. The FreeRide operates approximately every five minutes, seven days a week, and the MetroRide operates every 10 minutes during peak service times (6-9 a.m. and 3-6 p.m.), Mondays through Fridays. D Line trains will maintain their current, 15-minute frequencies between Littleton•Mineral and Denver Union stations.
• The H Line is operating between Florida and Southmoor stations. Customers traveling downtown will need to transfer to an E Line train. The E and H lines will both maintain 15-minute frequencies to support transfers at Southmoor Station.
• The L Line is suspended during the project, and Route 43 provides customers with continued connections along the downtown corridor.
• Bus Route 16 and Route ART also provide alternate service to the Colfax at Auraria Station. Bus stops near the project will remain open and operational during the reconstruction work.

RTD’s Impact Team will be at Southmoor Station to assist customers with any questions or concerns for making connections.
