By the time Congress created the Interstate Highway System in 1956, nearly all Chicago-area expressways were laid out, but federal funding pushed construction into high gear.

The abandoned Illinois & Michigan Canal provided a convenient right-of-way through the city for the Stevenson Expressway (I-55), opened in 1964.
