Chicago Skyway in the context of "Dan Ryan Expressway"

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.
