I-88 is long. This route is not contiguous to I-88 in New York. Since 2010, all of I-88 has been part of the Chicago–Kansas City Expressway. The highway also runs through the cities of Aurora, Naperville, DeKalb, and Dixon. ==History== Prior to its designation as an Interstate Highway, the route was known as IL 5, and before that, IL 190. The reason for I-88's original designation and continued existence as an Interstate has to do with a technicality in the old National Maximum Speed Law (NMSL). Originally passed in 1973, NMSL was amended in 1987 to permit speed limits on rural stretches of Interstate Highways only. Even though IL 5 was fully up to Interstate standards, it still had to carry a limit because of this wording in NMSL. The Illinois Department of Transportation (IDOT) and Illinois State Toll Highway Authority (ISTHA) petitioned the American Association of State Highway and Transportation Officials (AASHTO) to re-designate IL 5 as an Interstate, and in 1987, AASHTO approved the request and assigned the Interstate 88 numbering to the highway.〔 NMSL would be completely repealed only eight years later in 1995, but the I-88 shields remain up to this day, even though Illinois 110 shields are being posted throughout the entire Illinois I-88, since it is now part of the Chicago to Kansas City Expressway project, bannered with special "CKC" logos. , I-88 has no spur routes. None are planned for the near future. The proposed Prairie Parkway limited access highway will terminate at its north end via an interchange with I-88 near Kaneville, west of Illinois Route 47. 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「Interstate 88 (Illinois)」の詳細全文を読む スポンサード リンク
