Southeast Rail Extension at a glance

  • The Southeast Rail Extension is part of RTD’s 2004 voter-approved FasTracks plan to expand transit across the Denver metro region.
  • The extension will expand the Southeast Rail Line 2.3 miles from Lincoln Station to RidgeGate Parkway in Lone Tree.
  • The expansion encompasses three new stations: a Kiss-n-Ride at Sky Ridge Avenue near Sky Ridge Medical Center; one at the future Lone Tree City Center; and a 2,000-slot Park-n-Ride at RidgeGate Parkway.
  • The project has completed the Environmental Assessment (EA) needed to qualify for the Federal Transit Administration's (FTA) New Starts grant funding.
  • In July 2014, the RTD Board authorized a $207 million extension of the existing Southeast Light Rail Line farther south into Lone Tree. This action keeps the extension in the pipeline to receive a potential federal grant from the FTA.
  • Stakeholders in the southeast have committed to contributing $35 million to $40 million in cash, right-of-way and other items to get the light rail extension project completed.
