The Dan Ryan Expressway, often called "the Dan Ryan" by locals, is an expressway in Chicago that runs from the Jane Byrne Interchange with Interstate 290 (I-290) near downtown Chicago through the South Side of the city. It is designated as both I-90 and I-94 south to 66th Street, a distance of 7.44 miles (11.97 km). South of 66th Street, the expressway meets the Chicago Skyway, which travels southeast; the I-90 designation transfers over to the Skyway, while the Dan Ryan Expressway retains the I-94 designation and continues south for 4.03 miles (6.49 km), ending at an interchange with I-57. This is a total distance of 11.47 miles (18.5 km). The highway was named for Dan Ryan Jr., a former president of the Cook County Board of Commissioners.
