Lake Street ‘L’ Tracks at Dearborn Street, Chicago

Lake Street elevated 'L' tracks run above Lake Street at Dearborn Street in Chicago's Loop. The structure is part of the CTA's Loop Elevated, the rail circuit that carries rapid transit through the central business district. Built in stages in the late 19th century, Chicago's elevated system remains a core connection between downtown and surrounding neighborhoods.
