The 3-Trails Crossing Memorial Highway is the official name for a interchange in south Kansas City, Missouri that was once considered one of Missouri's most congested locations.〔http://missouri.sierraclub.org/SierranOnline/archive/GrandviewTriang.htm〕〔http://www.fox4kc.com/wdaf-firey-wreck-71-highway-story-62509,0,7349284.story〕〔http://www.kansascity.com/news/neighborhood/olathe/story/1299511.html〕 Although it is known as Grandview Triangle, it is not located in Grandview, a suburb of Kansas City. It is actually north of Grandview, still within the city limits of Kansas City. After several years of reconstruction, the interchange itself is largely congestion free during non-peak hours despite the high traffic on the highways approaching the interchange. During rush-hour moderate to major delays and numerous accidents are reported. The name "Three Trails Crossing" refers to the Santa Fe, Oregon, and California Trails that cross there.〔(3-Trails Crossing Signs Mark New Name for Historic Crossroads )〕 It is a major interchange of five major highways in the Kansas City area: I-49, I-435, I-470, US 50, and US 71. I-49/US 71 brings in traffic from the southeastern suburbs of the Kansas City area in Jackson and Cass counties. I-49 currently ends at the triangle, but the road continues northwest into Kansas City as US 71. The I-49 designation went into effect in December 2012. I-435 is a beltway around the Kansas City metropolitan area. I-470 is a major traffic corridor that connects southern Kansas City to the suburbs of eastern Jackson County, mainly Lee's Summit. US 50 travels concurrently with I-435 entering the Triangle, and then travels concurrently with I-470 at Exit 71A. The 3-Trails Crossing currently handles approximately 250,000 vehicles per day. Now that the reconstruction is completed, the interchange should be able to accommodate more than 400,000 vehicles per day. ==See also== * 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「Grandview Triangle」の詳細全文を読む スポンサード リンク
