North Metro Corridor became a victim of financial setbacks and it was feared that the line would not be built until 2044. RTD was able to avoid delaying the construction of the line when it accepted an unsolicited offer in 2013 to build out the full line in two stages. The first phase was completed in 2020. Northwest Rail Corridor (commuter rail) The Northwest Rail Corridor is a commuter rail project between Denver, Boulder, and Longmont. The completion of the proposed line, would consist of seven stations. The route would follow an existing railroad right-of-way from BNSF. The only segment of the line that has been completed to date has been up to Westminster Station. The station sits just south west of Federal and 72nd in Westminster. The line runs from Denver's Union Station to south Westminster, with plans for future segments in the distant future. The project was and still is a construction project part of the Eagle P3 project. Future segments are in an unknown phase at the moment and no construction has started on any other segments on the line. The remaining segments are currently predicted for completion by the year 2044. The announcement angered many voters in the cities and suburbs north of Denver who had approved a sales tax increase in 2004 to fund the FasTracks project. The downturn in the economy and significant cost increases and delays associated with building and operating the Northwest Corridor led to the initiation of the year-long "Northwest Area Mobility Study". This was an effort between northwest area governments and transportation partners that set out to recommend alternatives to the voter approved commuter rail line that could have possibly brought near-term mobility improvements to the northwest area. The study concluded in 2014 and made a number of recommendations that were adopted by the RTD Board of Directors in June 2014. One of the recommendations adopted was an interim express bus service called "Flatiron Flyer". In summer 2018, the U.S. 36 Mayors and Commissioners Coalition was gathering support from other members to ask RTD to provide an estimate for at least weekday rush hour commuter rail service along the original corridor to Longmont. The "Peak Service Plan" would carry 1,400 passengers per weekday. West Corridor (light rail) Preliminary work on the West Corridor light rail line began on May 16, 2007. During early stages of development, it was decided that
