It passed through Oklahoma City, Tulsa, and many smaller communities. West of the Oklahoma City area, it has been largely replaced by I-40; the few independent portions that are still state-maintained are now I-40 Business. However, from Oklahoma City northeast to Kansas, the bypassing I-44 is mostly a toll road, and SH-66 remains as a free alternate. ==History== The history of Route 66 in Oklahoma can be traced back to two auto trails—the St. Louis, Missouri–Las Vegas, New Mexico, main route of the Ozark Trails network, and the Fort Smith, Arkansas–Amarillo, Texas, Postal Highway. In the state highway system, approved in mid-1924, the portions of these in Oklahoma, which crossed at Oklahoma City, became SH-7 and SH-3 respectively.〔(State of Oklahoma, Preliminary Designation of the State Highway System ), approved August 28, 1924〕〔Rand McNally Auto Road Atlas, 1926, accessed via the (Broer Map Library )〕 US 66 was designated in late 1926, and followed these state highways with one exception: a new SH-39 was created to carry Route 66, leaving SH-7 at Commerce and heading east and north to the state line in the direction of Baxter Springs, Kansas.〔(Oklahoma State Highway System 1927 ), Progress Map as of November 1, 1927〕 (The short stub of SH-7 north of Commerce remained until it became part of US-69 in the mid-1930s.〔Oklahoma State Highway Commission, (Official State Highway Map of Oklahoma ), February 1934〕) Over the years, many portions of Route 66 west of Oklahoma City were replaced with I-40. On the other hand, the Turner Turnpike and Will Rogers Turnpike were built parallel to Route 66 east of Oklahoma City, and Route 66 remained on the old road as a free alternate to the turnpikes. Route 66 was entirely eliminated by the American Association of State Highway and Transportation Officials on April 1, 1985. In Oklahoma, the portions west of Oklahoma City that had not been rerouted onto I-40 became business loops of I-40 through Sayre, Elk City, Clinton, and El Reno. The still-independent route, starting at US-81 in southeastern El Reno, became SH-66, using surface streets except through Oklahoma City and Tulsa, where Route 66 had been rerouted onto the freeways. SH-66 ends at US-60 west of Vinita, where Route 66 overlapped US-60 and US-69 to east of Commerce. The remaining independent portion to the Kansas state line became part of a new US-69 Alternate.〔〔Oklahoma Department of Transportation, (Chronological History of US Highway 69 Alternate )〕 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「U.S. Route 66 in Oklahoma」の詳細全文を読む スポンサード リンク
