L Line Extension


  • Length (miles): 0.8
  • Vehicle Type: Light Rail
  • Stations: 3

At a Glance

  • The L Line Extension, or Central Rail Extension, is part of RTD’s 2004 voter-approved FasTracks plan to expand transit across the Denver metro region.
  • The extension will provide rail service between the existing L Line at 30th • Downing and the University of Colorado A Line at 38th • Blake. This will serve as a way for commuters in central downtown to connect with the line to the airport.
  • Two new stations are proposed: 33rd • Downing and 35th • Downing.
  • Service will be provided by single light rail vehicles that complete round-trips, in-traffic transit operations between 30th • Downing and 38th • Blake.

Project Overview

  • As part of the planning process, an Environmental Evaluation (EE) was conducted, including an analysis of alternative alignments and station locations, identification of potential impacts, and a recommendation for ways to minimize any impacts throughout the corridor.
  • 2010: RTD Board of Directors adopted the EE for the Central Rail Extension.
  • 2013: The CRE 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.
  • 2014: The CRE mobility study was complete and provided several options for consideration.
  • 2015: Basic engineering was completed. Once final funding is identified, final design and construction will begin
