Interstate 94 (I-94) generally runs north–south through the northeastern portion of theIn the U.S. state of Illinois, in Lake and Cook counties. It is marked east–west in Illinois in accordance with its general alignment across the country, although some entrances on the Tri-State Tollway have north or south I-94 signs. I-94 in Illinois is 78.00 miles (125.53 km) long.
The William G. Edens Expressway (also known as the Edens Parkway and the Edens Superhighway) is the main major expressway north from the city of Chicago to Northbrook, Illinois. Only the short portion from the spur ramp to the expressway's end in Highland Park does not carry I-94. It was the first expressway in Chicago and was opened on December 20, 1951. It has three lanes in each direction. The original name of the expressway was the Edens Parkway, named after William G. Edens, a banker and early advocate for paved roads. He was a sponsor of Illinois' first highway bond issue in 1918.
Wisconsin to Downtown Chicago
I-94 traverses rural and suburban areas in Lake County, and serves Six Flags Great America and the Gurnee Mills mall; extensive office developments and residential districts in southern Lake County and the North Shore region of Cook County, and serves the Old Orchard Shopping Center; the length of the city of Chicago, running just west of the Chicago Loop on the Kennedy Expressway.
I-94 has 6 lanes (3 in each direction) from the state line to Illinois Route 173 (Rosecrans Road) with wide shoulders planned to be 8 by 2015-2016 (same time as the I-94 in WI work). At this point it becomes 8 lanes wide until just north of Deerfield Road where it widens further to 10 lanes as it approaches Interstate 294 and the Edens Spur. This is where 3 lanes branch off and begin I-294 while 2 lanes for I-94 head east onto the Edens Spur which only has four lanes total (two in each direction).
The highway turns south and widens back to six lanes on the Edens Expressway, and to ten lanes (four lanes in each direction + two reversible lanes) along the Kennedy Expressway. At Ohio Street, the reversible lanes terminate and the highway has 10 lanes to the Circle Interchange, where the left lane ends and the right lane exits onto the Eisenhower Expressway.
Until 2010, mileposts along the portion of I-94 that are part of the Tri-State Tollway reflect the distance from the southeastern terminus of the tollway, that led to a counterintuitive increase in the mile numbers as one proceeds "west." In 2010, the mile markers have been renumbered to indicate mileage of Interstate 94 traveled in Illinois, increasing from the Wisconsin border to the Indiana border. 
Downtown Chicago to Indiana
South of downtown Chicago, I-94 serves the southeast suburbs of Chicago, including Dolton, Calumet City, and South Holland, Illinois, until it joins Interstate 80 on the Kingery Expressway, which finally enters Indiana east of Lansing, Illinois.
I-94 has ten lanes (five in each direction) from the exit ramps of the Circle Interchange to the Stevenson Expressway. It then splits into a 14 lane expressway on the Dan Ryan, with three and four lanes alternating between the local and express lanes in both directions. At the Chicago Skyway, a two lane ramp carries traffic to I-90, leaving ten lanes (five in each direction) running south to the I-57/I-94 junction.
From I-57 to Cottage Grove Avenue, I-94 has four lanes (two lanes each way), with six lanes (three lanes each way) between Michigan Avenue and Cottage Grove Avenue. The freeway connection ramp to Stony Island Avenue has four lanes (two in each direction). I-94 then has six lanes (three in each direction) south to I-80. On the ramps to and from I-80, I-94 has two lanes in each direction. On I-80 itself, I-94 widens to eight lanes (four in each direction) to the state line.
The section including the Southland Interchange with I-80 and 294 was reconfigured as part of the Kingery Expressway reconstruction project, completed in 2007, including 4 lanes south of 159th Street, with the split between I-80 and 94 East to the left, and I-80 West, I-294 North, and Ill. 394 South on the right located north of the 170th St. overpass. The configuration of I-80 and 94 is discussed in connection with the Kingery Expressway.
Interstate 494 (and later Interstate 694) was originally planned to serve as a loop in Chicago and follow Lake Shore Drive along Lake Michigan. After local opposition prevented I-494 and I-694 from being completed, both numbers were completely dropped. Portions of the old I-494/I-694 exist as US 41/Lake Shore Drive and the Ohio Street connector. In addition, I-494 was also planned at one point to be a western bypass of Chicago, as the Crosstown Expressway.
The Edens Expressway section of I-94 was last rehabilitated from 1978 through 1980. From 2007 to 2009, I-94 was widened from six to eight lanes between Illinois Route 173 (Rosecrans Road) and Illinois Route 22 (Half Day Road).
On April 4, 2008 the Illinois Department of Transportation (IDOT) closed one lane in each direction for the entire length of the freeway. The closures lasted until August 2008, occurred in advance of patching and resurfacing of the mainline. In addition, the $42.8 million project will rehabilitate six bridges and improve drainage at four underpasses.
The Calumet Expressway was originally 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 Illinois 1, Alternate U.S. 30, and certain portions as U.S. 6 and Illinois 83, but Illinois 1 returned to Halsted Street, and U.S. 6 and Illinois 83 were routed onto Torrence Avenue. In 1962, the connection between the Calumet Expressway and Dan Ryan Expressway opened, and is now signed as part of the Bishop Ford.
In 2006-2007, the portion south of 159th Street was reconstructed as part of the Kingery Expressway-Southland Interchange project. The section between 159th Street and Martin Luther King, Jr. drive was rehabilitated and resurfaced in Summer and Fall 2009.
Various section of I-94 take on localized names.
