The Future of the L Line

New Rail in New Neighborhoods with the L Line Extension

The Central Rail Extension would connect existing downtown rail service with the 38th & Blake Station on the University of Colorado A Line. The L Line would provide rail service between downtown Denver and the 38th & Blake Station, and act as a “loop” around downtown. The extension will require new track.

RTD Board of Directors adopted the EE for the Central Rail Extension
The Central Rail Extension underwent further analysis, including a study to identify the most feasible transit route and operating plan to provide a direct connection between 38th & Blake and downtown Denver.
The Central Rail Extension Mobility Study is complete and provided several options for considerations. Once final funding is identified, final design and construction will begin. In the meantime, basic engineering design started is expected to be 30% complete in 2015.
Basic engineering was completed. Once final funding is identified, final design and construction on the L Line extension will begin.
