With the opening of the Southeast Corridor, many regional bus routes that provided service from the North Metro to Denver Tech Center were replaced by service to Union Station and light rail from Union Station to the Belleview light rail station. Several regional bus routes to and from the South Metro were also eliminated by the openings of the Southeast & Southwest Corridors, replaced by feeder routes to light rail.
