for Citizens Area Transit, once Las Vegas Transit ceased operations. Originally, the DTC only had 23 bays, with two of them unnumbered. In 1999, the city expanded the terminal by building a northern plaza which required closing down Mesquite Ave. in the area. The DTC remained under ownership of the City of Las Vegas until July 31, 2009 when the city discontinued their CityRide transit system and transferred control of the terminal to the RTC. The RTC closed the aging terminal on November 7, 2010, with the grand opening of the Bonneville Transit Center.
