The future of the B Line

The start of great things to come!

Westminster Station represents the centerpiece of the South Westminster revitalization project that will bring new open space along Little Dry Creek as well as high density and mixed use development projects that will surround and enrich the Westminster Station.

Additionally, the B Line to Westminster is the first segment of future rail construction that will one day connect Union Station to Longmont, passing through Broomfield, Louisville, Boulder and Gunbarrel, which is part of the FasTracks program.
