The Crosstown Expressway (Interstate 494, as it was dubbed), was a proposed highway route in Chicago, Illinois in the 1960s through the 1970s. ==Route description== The highway was to begin from a connection with the Kennedy Expressway and Edens Expressway (Interstates 90 & 94) near Montrose Avenue on the city's Northwest Side. It was to follow an alignment parallel, and adjacent to the Belt Railway of Chicago, approximately one-half mile east of Cicero Avenue and extend southerly over railroad right-of-way through the West Side of Chicago, and across the Sanitary and Ship Canal to a connection with the Stevenson Expressway (Interstate 55). South of this confluence, the route would continue south in a reverse direction, split-arrangement with the northbound highway lanes depressed along Cicero Avenue and the southbound lanes depressed along the Belt Railway of Chicago tracks. Continuing south past the proposed traffic interchange at Chicago Midway International Airport, the expressway alignment was to turn southeasterly at 67th Street and continue over Belt Railway right-of-way to Lawndale Avenue then turn easterly towards the Dan Ryan Expressway along Norfolk Southern Railway right-of-way (now Metra-South West Service) and 75th Street to an interchange with the Dan Ryan Expressway (Interstate 94) north of 91st Street. Extra lanes were planned to extend north from the proposed Dan Ryan/Crosstown interchange to connect with the Chicago Skyway (Interstate 90) near 66th and State Streets. The Crosstown Expressway was designed as no mere highway plan. It was conceived as a massive community improvement project—a standard by which many new highway projects in the world would be based. It was heralded by former Mayor of Chicago Richard J. Daley as the "Roadway of the Future". The I-494 number was originally to be used for a freeway upgrade of Lake Shore Drive that was also cancelled; when the Crosstown Expressway inherited that number, the LSD proposal was then renumbered to I-694. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Crosstown Expressway (Chicago)」の詳細全文を読む スポンサード リンク
