The B Line, also known as the Northwest Rail Line during construction, is a commuter rail line which is part of the commuter and light rail system operated by the Regional Transportation District in the Denver metropolitan area in Colorado.[2] Part of the FasTracks project, the first 6.2-mile (10 km) section from downtown Denver to south Westminster opened on July 25, 2016.[3] If fully built out, estimated around 2042,[4] the B Line will be a 41-mile (66 km) high-capacity route from Denver Union Station to Longmont, passing through North Denver, Adams County, Westminster, Broomfield, Louisville and Boulder.[2]
