Westminster, and a maintenance facility into a single contract. Denver Transit Partners, the consortium of companies RTD selected to lead the Eagle P3 project, is responsible for the design, construction, financing, operation and maintenance of the rail lines in the contract. Construction broke ground on the Gold Line on August 26, 2010. In August 2011, Secretary of Transportation Ray LaHood committed $1 billion in federal money to the Eagle P3 project. In December LaHood approved a $280 million loan to advance construction. As of June 2013, the project is on track to open the rail lines under contract in 2016. East Rail Line (commuter rail) Being constructed as part of the Eagle P3, the East Rail Line is a commuter rail line between downtown Denver, Aurora, and Denver International Airport using electric multiple unit (EMU) commuter trains. To expedite travel time between downtown Denver and Denver International Airport, only six stations will be located on the line. Construction started in August 2010, and the line opened to the public on April 22, 2016. Gold Line (commuter rail) The second full line funded under the Eagle P3, the Gold Line is an commuter rail corridor that will run from Denver Union Station to Wheat Ridge, passing through Adams County and Arvada. As with the East Corridor, the RTD Board of Directors chose EMU commuter trains to run on the Gold Line. Seven new stations—with an already existing station at Union— were built for the line. It opened on April 26, 2019. I-225 Corridor (light rail) The I-225 Corridor is light rail line running through Aurora and facilitate a circumferential link between the Southeast Corridor and the East Line. The project will include seven new stations and provide 1,800 new parking spaces. Construction began in the spring of 2012 on a short section of the line as part of a joint contract with CDOT. Following an unsolicited proposal from Kiewit Infrastructure Co. funding was secured for the full line which opened on February 24, 2017. North Metro Corridor (commuter rail) The North Metro Corridor is a commuter rail line that runs along an existing railroad right-of-way from Denver to 160th Avenue in Thornton. The line has eight stations on its route. In 2009, RTD paid $117 million to purchase the right-of-way from Union Pacific in preparation for the buildout of the North Metro line.
