Illinois Route 394 (IL 394), also known as the Calumet Expressway, is a 14 miles 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).
