In May 2024, RTD began a multi-phased project to reconstruct its oldest light rail infrastructure. This major reconstruction project is the first of its kind in RTD’s history and will ensure the long-term integrity of the network.

After more than 30 years of continual operation, RTD is investing in its oldest rail infrastructure to ensure the long-term integrity of the network. Light rail service began in Denver on October 7, 1994, with 5.3 miles of track connecting 30th Avenue and Downing Street to Interstate 25 and Broadway. Much of today’s downtown track infrastructure, commonly referred to as the Downtown Loop, has been in place since the line was first constructed and opened for service. This original section of track has expanded over the years to now serve 10 rail stations on the D, H, and L lines, with street-level trains operating adjacent to pedestrians and vehicular traffic. More than 300 light rail trains circle the Downtown Loop every day, so it is critically important RTD maintain this asset in a state of good repair for the next 30 years.
