The D Line is a light rail line which is part of the rail system operated by the Regional Transportation District in the Denver–Aurora Metropolitan Area in Colorado. The D line was the first line in the system when it opened in 1994, traveling from 30th & Downing in Five Points, through downtown Denver, and terminating at I-25 & Broadway as the Central Corridor. It was extended along the Southwest Corridor in July 2000. Because it was the first and only line in the system it had no letter or color designation until the Central Platte Valley Spur opened on April 5, 2002, although on maps it was designated as Route 101.
