Interstate 80 (I-80) is a transcontinental limited-access highway in the United States that runs from downtown San Francisco, California to Teaneck, New Jersey in the New York City Metropolitan Area. The highway was designated in 1956 as one of the original routes of the Interstate Highway system. Its final segment was opened to traffic in 1986. It is the second-longest Interstate Highway in the United States, following Interstate 90. The Interstate runs through many major cities including Oakland, California, Sacramento, California, Salt Lake City, Utah, Omaha, Nebraska, Des Moines, Iowa and Toledo, Ohio, and passes within of Chicago, Cleveland, Ohio and New York City. I-80 is the Interstate highway that most closely approximates the route of the historic Lincoln Highway, the first road across America. The highway roughly traces other historically significant travel routes in the Western United States: the Oregon Trail across Wyoming and Nebraska, the California Trail across most of Nevada and California, the first transcontinental airmail route, and except in the Great Salt Lake area, the entire route of the First Transcontinental Railroad. From near Chicago, Illinois east to near Youngstown, Ohio, Interstate 80 is a toll road, containing the majority of both the Indiana Toll Road and the Ohio Turnpike. I-80 runs concurrent with Interstate 90 from near Portage, Indiana to Elyria, Ohio. In Pennsylvania, I-80 is known as the Keystone Shortway, a non-tolled freeway that crosses rural north-central portions of the state on the way to New Jersey and New York City. ==Route description== |- |CA | |- |NV | |- |UT | |- |WY | |- |NE | |- |IA | |- |IL | |- |IN | |- |OH | |- |PA | |- |NJ | |- class="sortbottom" |Total | |} 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 80」の詳細全文を読む スポンサード リンク
