Oak Park station

Oak Park is a station on the Chicago Transit Authority's 'L' system situated between the Ridgeland and Harlem stations on the Green Line. It is located at Oak Park Avenue and South Boulevard in the village of Oak Park, Illinois and is the closest station to the Frank Lloyd Wright Home and Studio.
Oak Park station was opened on January 25, 1901, by the Lake Street Elevated Railroad as a surface-level station on the line that ran parallel to the former Chicago and Northwestern Railway line . Both lines created an unsafe grade crossing, especially as the community moved from horse-powered vehicles to the automobile. When the C&NW elevated its line between 1908 and 1909, it created a blind spot for traffic trying to cross the Lake Street Line.
