At a Glance

  • Eagle P3 is part of RTD’s 2004 voter-approved FasTracks plan to expand transit across the Denver metro region.
  • The $2.2 billion project comprises the A Line and G Line, the first segment of the B Line to Westminster, procurement of 56 commuter rail cars and a commuter rail maintenance facility, all scheduled for completion in 2016.
  • P3, or public-private partnership, is an innovative financing and delivery method in which a public entity partners with the private sector. The private team invests its own money and assumes much of the risk on the project. That allows the public entity to spread out large upfront costs while preserving public cash for early construction.
  • Funding for Eagle P3 comes from federal grants and loans, RTD sales taxes and the contractor’s financial contribution. The project received a $1.03 billion Full Funding Grant Agreement from the Federal Transit Administration.
  • RTD entered into a 34-year agreement with Denver Transit Partners (DTP) under which it will pay DTP to operate and maintain the system; DTP repays its private financing from that amount, much like home mortgages are repaid.
