Project Overview

  • 2001: RTD completed an investment study to evaluate north I-25 transit from Denver to Brighton.
  • 2005: RTD conducted a scoping study to build on previous analyses of the corridor.
  • 2006: RTD began an Environmental Impact Statement (EIS) process to analyze transit options for the corridor. The EIS built on previous transit alternative studies, possible adverse implementation impacts and subsequent mitigation.
  • 2009: RTD purchased most of the N Line right-of-way from Union Pacific Railroad for $119 million.
  • 2011: RTD issued a final EIS, identifying community benefits and possible impacts of a new transit service in the area; the team received a Federal Transit Administration Record of Decision.
  • 2012: RTD committed funding to build the project’s first phase from Union Station to the National Western Stock Show Station.
  • 2013: RTD received an unsolicited proposal to build the line, opened a competitive bidding process, and later awarded a design-build contract to Regional Rail Partners (RRP) to complete the line to 124th•Eastlake, with options to extend it as funds become available.
  • 2014: The N Line broke ground in March; design of the project reached 60 percent completion in September; and North Metro received rail delivery and completed tie-in work at Union Station in November.
  • 2015: Utility relocation and right-of-way acquisition underway; 90 percent design completion; construction began in summer 2015.
  • 2016: Construction was underway throughout every segment of the project.
  • 2018: The project team began construction on the Thornton Crossroads 104th Station parking garage. All rail track is in place from Union Station to the Eastlake 124th Station and tie-in work to Union Station is complete. All bridges and retaining walls have been completed.
  • 2019: Wires on the North Metro Line went live in March and trains began testing on the corridor in April. Safety outreach to the schools and communities is ongoing.
