Interstate 94 in Illinois
Interstate 94 (I-94) generally runs north–south through the northeastern portion of the US state of Illinois, in Lake and Cook counties. It is signed east–west in Illinois in accordance with its general alignment across the country, with west signage aligned with northbound travel and east signage aligned with southbound travel. I-94 in Illinois is 61.53 miles (99.02 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. 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 Grant Edens (1863–1957), a banker and early advocate for paved roads. He was a sponsor of Illinois's first highway bond issue in 1918.
From the southern terminus of the Edens, I-94 follows part or all of several other named highways; joining I-90 on the Kennedy Expressway and the Dan Ryan Expressway through the center of Chicago, following the Bishop Ford Freeway through the southside of Chicago to I-80, where it joins the Kingery Expressway before entering Indiana.
The control cities for I-94 generally are Wisconsin or Milwaukee to the north and west, Chicago or the Chicago Loop for those heading to the central portion, and Indiana to the south and east.
I-94 traverses rural and suburban areas in Lake County and the length of the city of Chicago, running just west of the Chicago Loop on the Kennedy Expressway, and serves Six Flags Great America, the Gurnee Mills mall, extensive office developments and residential districts in southern Lake County and the North Shore region of Cook County, and Westfield Old Orchard.
Entering Illinois from Wisconsin, I-94 becomes the Tri-State Tollway just after exit 1B (Skokie Highway), with eight lanes (four in each direction), until just north of Deerfield Road where it widens further to 10 lanes as it approaches I-294 and the Edens Spur. This is where three lanes for the Tri-State Tollway branch off and begin I-294 while two 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 as it merges with US Route 41 (US 41) and becomes the Edens Expressway, and then widens to 10 lanes (four lanes in each direction plus two reversible lanes) along the Kennedy Expressway. At Ohio Street, the reversible lanes terminate and the highway has 10 lanes to the Jane Byrne Interchange, where the left lane ends and the right lane exits onto the Eisenhower Expressway (I-290).
Until 2010, mileposts along the Tri-State Tollway portion of I-94 reflected 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 milemarkers were renumbered to indicate mileage of I-94 traveled in Illinois, increasing from the Wisconsin border to the Indiana border.
