The Garfield Park elevated was replaced by the Congress line on June 22, 1958, pioneering the world's first use of rail rapid transit and a multi-lane automobile expressway in the same grade-separated right-of-way. (Pacific Electric Railway "Red Car" tracks ran in the median of the Cahuenga Parkway in Los Angeles from 1944 until its expansion into the Hollywood Freeway in 1952, but the Pacific Electric service was an interurban streetcar rather than true rapid transit.) The new line connected with the Milwaukee-Dearborn Subway at the Chicago River and extended westward to Des Plaines Avenue in Forest Park. Loomis Ramp, built at this same time, permitted Douglas trains to be rerouted through the subway as well combining the Logan Square, Garfield Park (now Congress) and Douglas routes into the second through service in Chicago, the Congress/Douglas-Milwaukee Line.
