Clinton is a subwaystation on the Chicago Transit Authority's 'L' system, serving the Blue Line and the West Loop neighborhood of the larger Near West Side community area. The Congress Branch of the Blue line opened in June 1958, and connected to the existing Dearborn subway at LaSalle. It is the closest 'L' station to Union Station, which doubles as Chicago's Amtrak station and the downtown terminal for several Metra lines. It is also the closest station to Chicago's Greyhoundbus terminal. Union Station is two blocks north, while Greyhound is one block west.
It is also the deepest station on the CTA system.[2]
