Interstate 465 (I-465), also known as the USS Indianapolis Memorial Highway, is the beltway circling Indianapolis, Indiana, United States. It is roughly rectangular in shape and has a perimeter of approximately 53 miles (85 km). It lies almost completely within the boundaries of Marion County, except for two short sections on the north leg in Boone and Hamilton Counties. It crosses I-65, I-69, I-70 and I-74, and provides additional access to I-65 via I-865. An $800 million project was completed in the fall of 2012 to refurbish the western edge of the loop. ==Route description== Except for I-65 and I-70, no numbered highways run through downtown Indianapolis. All highways that continue from one side to the other are routed around the city, concurrent with I-465: *Interstate 74, counterclockwise from exit 16 to exit 49 *U.S. Highway 31, counterclockwise from exit 2 to exit 31 *U.S. Highway 36, counterclockwise from exit 13 to exit 42 *U.S. Highway 40, counterclockwise from exit 12 to exit 46 *U.S. Highway 52, clockwise from exit 25 to exit 47 (originally counterclockwise from exit 20 to exit 48〔(1969 Indianapolis map ) (note that the highlighting is wrong, as (exit 47 was a partial interchange ), so US 52 had to use exit 48 and Shadeland Avenue (State Road 100))〕) *U.S. Highway 421, counterclockwise from exit 49 to exit 27 *State Road 37, counterclockwise from exit 4 to exit 37 (originally only from exit 4 to exit 2〔(【引用サイトリンク】title=USGS 1984 map )〕) *State Road 67, counterclockwise from exit 8 to exit 42 *Future Interstate 69, Clockwise from Exit 37 to Exits 3-8 (Proposed Route) The approximately one-mile section between exits 46 and 47 carries eight routes — I-465, US 31, US 36, US 40, US 52, US 421, SR 37 and SR 67. It will carry Interstate 69 in the future. In most cases, markers other than I-74's are not posted along I-465 itself; rather, signs on the onramps direct traffic following a particular route to follow I-465 to a particular exit to continue on that route. 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 465」の詳細全文を読む スポンサード リンク
