Interstate 240 (abbreviated I-240) is an Interstate Highway in Oklahoma, USA, that runs 16.22 miles (26.1 km) west from Interstate 40 to Interstate 44 in southern Oklahoma City. After its terminus in southwest Oklahoma City, the main I-240 roadbed becomes Interstate 44 and Airport Road toward Will Rogers World Airport. The interstate overlaps SH-3, the longest Oklahoma state highway, for its entire length. Major destinations along the route include Crossroads Mall, Tinker Air Force Base, and the heavily populated Southside of Oklahoma City. With just under of commercial space,〔Based on first quarter 2009 survey of buildings within 1/2 mile either side of I-240 between Will Rogers Airport I-44 and SH-77H (Sooner Road).〕 I-240 is a major corridor of retail, industrial and office space. As of 2012, however, the corridor included some "pockets of shuttered stores and creeping shabbiness" and local planners were in the first stages of efforts to revitalize the corridor.〔Richard Mize, ("Urban Land Institute, businesses, city aim to revamp I-240 in south Oklahoma City" ), ''The Oklahoman'', March 10, 2012.〕 I-240's service road is named S.E. 74th Street. ==Route description== From the western terminus at I-44, I-240/US-62/SH-3 runs east towards Interstate 35. The western half is the busier of the two sections, serving the Southside area of Oklahoma City and traffic headed to the airport. This segment has a configuration of ramps that causes much weaving and many accidents. An entrance ramp will merge onto the highway, forming a new lane. This new lane will then become an Exit Only lane for the next exit. However, the exits are not spaced very far apart, causing entering and exiting traffic to conflict. (For a satellite photo, see.〔(【引用サイトリンク】title=Lane Configuration )〕 ) Signs were installed in October 2004 designating the western half of I-240 as the ''Keith Leftwich Memorial Loop'', in honor of a state senator who died recently.〔Stuve, Eric. (Interstate 240 ). ''OKHighways''. URL accessed 8 March 2006.〕 I-240 meets I-35 at a cloverleaf interchange. US-62 splits off to join with I-35 northbound at this interchange. The section of I-240 east of I-35 exists primarily to serve the now-closed General Motors plant and Tinker Air Force Base. Crossroads Mall can also be accessed via Exit 4C for Pole Road. This section is much less traveled, having only four lanes (two in each direction) for much of its length. At I-240's eastern terminus with I-40, motorists traveling eastbound on I-240 are forced to merge onto I-40 eastbound—there is no I-40 West off-ramp. (Those wishing to take I-40 West must exit off of I-240 a mile earlier at Anderson Road, a surface street, and travel on it northbound until they reach I-40, or continue east on I-40 before turning around at Choctaw Road.) 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 240 (Oklahoma)」の詳細全文を読む スポンサード リンク
