Illinois Route 394 (IL 394), also known as the Calumet Expressway, is a 14.6-mile-long (23.5 km) four-lane state highway that travels north from a junction with IL 1 south of Crete to an interchange in South Holland with Interstate 294/Interstate 94/Interstate 80 (I-294/I-94/I-80, Tri-State Tollway/Bishop Ford Freeway; this route is an extension of, but not part of the latter freeway). Although not an Interstate Highway, Illinois 394 is an Interstate-standard highway from its junction with Sauk Trail at Sauk Village to its northern terminus at the I-294/I-94/I-80 interchange in South Holland. IL 394 functions as a bypass of IL 1 to the west, of which it was formerly part, and provides access to southern suburbs of Chicago. From Wikipedia
