R Line (RTD)

The R Line or Aurora Line/I-225 Rail is a Regional Transportation District (RTD) light rail line currently under construction in Aurora, Colorado. When the line opens in 2016, it will travel over existing portions of the RTD Light Rail system to serve stations in neighboring Denver, Greenwood Village, Centennial and Lone Tree. The line was designated as the “R” line, reflecting the letter R’s in “Aurora” and “Ridgegate”.
