The John F. Kennedy Expressway is a nearly freeway in Chicago, Illinois, United States. Portions of the freeway carry I-190, I-90 and I-94. The freeway runs in a southeast–northwest direction between the central city neighborhood of the West Loop and O'Hare International Airport. The highway was named in commemoration of 35th US President John F. Kennedy. It conforms to the Chicago-area term of using the word expressway for an Interstate Highway without tolls. The Kennedy's official endpoints are the Jane Byrne Interchange with Interstate 290 (Eisenhower Expressway/Ida B. Wells Drive) and the Dan Ryan Expressway (also I-90/94) at the east end, and the O'Hare Airport terminals at the west end. I-190 runs from the western terminus at O'Hare Airport for , where it meets I-90 and runs a further , before joining with I-94 for the final . Traveling eastbound from O'Hare, the Kennedy interchanges with the eastern terminus of the Jane Addams Memorial Tollway (I-90) and with the Tri-State Tollway (I-294) at a complex junction just west of Illinois Route 171 (IL 171, Cumberland Avenue). The Kennedy later merges with the southern end of the Edens Expressway (I-94) at Montrose Avenue; the Kennedy (at this point both I-90 and I-94) then turns south to its junction with the Dan Ryan and Eisenhower Expressways and Ida B. Wells Drive at the Jane Byrne Interchange in downtown Chicago. With up to 327,000 vehicles traveling on the Kennedy daily, the Kennedy and its South Side extension, the Dan Ryan, are the busiest roads in the Midwest. History The Kennedy was originally constructed along the route of Avondale Avenue, an existing diagonal street, and the C&NW Northwest Line corridor, in the late 1950s and completed on November 5, 1960. Originally named the Northwest Expressway for its general direction of travel, the Chicago City Council voted unanimously on November 29, 1963—one week after the assassination of President Kennedy—to rename the highway the John F. Kennedy Expressway. Until 1978, the Kennedy Expressway was marked as I-94 and Illinois Route 194 (IL 194), I-90 and I-190 replaced IL 194 and thus the Eisenhower Expressway was renamed from I-90 to I-290. The express portion of the freeway was last reconstructed from 1992 through 1994, when the existing express lanes, which previously were reversed by hand, were modernized. In addition, all aspects of the express lanes system were computerized, so that the process could be controlled at both
