Illinois Route 394 (IL 394), also known as the Calumet Expressway, is a 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. Route description IL 394 begins as a four-lane arterial at a junction with IL 1 south of Crete, continuing as through traffic from IL 1 north. The highway curves to the east before assuming a north–south alignment, running parallel to IL 1 to the east, heading north as a surface street arterial, before becoming an Interstate-standard freeway at an intersection with Sauk Trail in Sauk Village. Shortly thereafter, the freeway meets U.S. Highway 30 (US 30, Lincoln Highway) in Ford Heights. Continuing northward, IL 394 ends at an interchange with I-294/I-94/I-80 (Tri-State Tollway/Bishop Ford Freeway) interchange in South Holland. History Before taking the IL 394 designation, the route was a former alignment of IL 1. In the 1950s, a freeway, then known as the Calumet Expressway, was constructed south of Chicago as an extension of Doty Avenue. There were traffic lights at the intersections of Doty with 111th, 115th, and 130th, but interchanges were built in the early 1960s. The expressway was originally designated as IL 1, Alternate US 30, and certain portions as US 6 and IL 83. By 1964, IL 1 was restored to its old alignment along Halsted Street, and US 6 and IL 83 were routed onto Torrence Avenue, while the IL 394 designation was applied to the expressway south of the portion designated as I-94. At this time, IL 1 was discontinued north of I-57. In 1962, the connection between the Calumet Expressway and Dan Ryan Expressway opened and is now signed as part of the Bishop Ford. In 1996, the Calumet Expressway was renamed in honor of Bishop Louis Henry Ford, the leader of the Church of God in Christ who had died the previous year. In 2006 and 2007,
