 The Dan Ryan Expressway runs from the Circle Interchange with I-290 near downtown Chicago through the south side of the city. It is designated as both Interstate 90 and Interstate 94 north of 66th Street, a distance of 7.44 miles (11.97 km), and only Interstate 94 south of its connection with the Chicago Skyway near 66th Street, a distance of 4.03 miles (6.49 km). This is a total distance of 11.47 miles (18.5 km).[1]
[edit] Route descriptionOn an average day, between 71,000 and 307,100 vehicles use part of the Dan Ryan (2005 data).[1] The Dan Ryan and its North Side extension, the Kennedy Expressway, are the busiest roads in Illinois. Utilizing an express-local system, the Dan Ryan has fourteen lanes of traffic, seven in each direction, with four of those express lanes and the other three providing access to exits. Despite its width, the Dan Ryan is prone to traffic jams. The Dan Ryan's express-local system is similar to that of Toronto's Highway 401. As with the Kennedy Expressway, the posted directions on the Dan Ryan are different than the actual compass direction of the expressway, which causes confusion to many travelers. The Dan Ryan for its entire 12-mile (19 km) length runs north and south. However the Dan Ryan is just a very small part of Interstates 90 and 94, which are signed as east-west routes. Therefore, one who is traveling "west" on I-90/94 is actually driving north on the Dan Ryan; similarly, "east" is really south. Chicagoans typically refer to the directions of travel as "inbound" and "outbound" from downtown. Over 2½ miles of continuous high-rise housing projects (Stateway Gardens and the Robert Taylor Homes) formerly lined the east side of the freeway from 35th Street south to Garfield (55th Street). However, nearly all of these buildings have been vacated and demolished as part of the CHA's transformation plan. The Red Line of the Chicago Transit Authority runs in the median of the Dan Ryan. That section opened on August 24, 1969 and is not unlike the Yonge-University-Spadina subway line running along the median of Allen Road in Toronto. The control cities for the Dan Ryan Expressway are Indiana and Chicago Loop. [edit] HistoryThe Dan Ryan was opened in 1962 and named for Dan Ryan, Jr., the President of the Cook County Board of Commissioners. During planning stages it was also known as the South Route Expressway. [edit] Reconstruction history In 1988-1989, the northern three miles (5 km) of the Dan Ryan, known as the Elevated Bridge, were completely reconstructed.[2] In 2006 and 2007, IDOT reconstructed the entire length of the Dan Ryan Expressway, including the addition of a travel lane from 47th Street to 95th Street. The project was the most massive expressway reconstruction plan in Chicago history. The total cost of the project was US$975 million, nearly twice the US$550 million original estimate for the project.[3][4] [edit] Exit listThe entire route is in Chicago, Cook County.
