Interstate 494 (I-494) is a loop route making up part of a beltway of Interstate 94, circling through the southern and western portions of the Minneapolis – Saint Paul metropolitan area in Minnesota. The 43-mile (69 km) road is coupled with Interstate 694 (which circles the northern edge of the Twin Cities metro area) at each end, and composes more than half of the major beltway of the region. I-694 / I-494 also act as loop routes for Interstate 35E and Interstate 35W. I-494 has a few intersections with other interstates: *Interstates 94 and 694 at Woodbury / Oakdale *Interstate 35E in Mendota Heights *Interstate 35W in Bloomington *Interstate 394 in Minnetonka *Interstates 94 / 694 (concurrent) in Maple Grove The speed limit on I-494 is 60 miles per hour (100 km/h). Interstate highways outside of the loop in Minnesota may be signed as high as 70 mph (110 km/h). Most highways inside the loop are signed at speeds of 55 mph (90 km/h) or lower, though a few exceptions were added in September 2005, allowing speeds of up to in some places. Those roads had been signed at or higher up until the gasoline crisis of the 1970s. ==Route description== Exit numbering of Interstate 494 is unusual in that it begins at the Minnesota River heading westbound (between Mendota Heights and Bloomington), and continues clockwise around the entire beltway. The last exit is #71 to Pilot Knob Road. The most significant landmark on the length of I-494 is Mall of America, just south of the intersection of I-494 and State Highway 77. Legally, the route of Interstate 494 is defined as part of unmarked legislative route 393 in Minnesota Statutes § 161.12(5). () Interstate 494 is not marked with this legislative number along the actual highway. 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 494」の詳細全文を読む スポンサード リンク
