Each exit in the highway loop is numbered 2 and suffixed with every letter of the alphabet except I, O, and Z (I and O look similar to 1 and 0 on the exit tabs; Z is not needed), although some of the exits are currently under construction/renovation and closed to traffic. The entire circumference of the loop is just over four miles (6 km). ==Description== Alphabetically, the letter suffixes begin with A in the northwest corner of the loop and proceed forward in a clockwise direction around the loop. Eastbound on the north side of the loop (EB I-70/NB I-35), one encounters A through G; then H through M southbound on the east side (EB I-70/SB US 71); then N through U westbound on the south side (WB I-670); and finally V through Y northbound on the west side (NB I-35 alone). Interstate 70 enters the southeast corner of the loop and moves north forming the east and north sides of the loop and exiting in the northwest corner. Exits on I-70 range from 2A to 2M. Interstate 35 enters the loop at its northeast corner, joining I-70 on the north side and forming the west side of the loop before exiting in the southwest corner. Exits on I-35 range from 2F to 2A while it overlaps I-70, and 2Y to 2U after I-70 exits the loop. Interstate 29 does not enter the loop. It begins at the northeast corner and continues north, concurrent with I-35. These two leave the loop via the Christopher S. Bond Bridge and split several miles north. Interstate 670 forms the south side of the loop. I-670 splits from I-70 in Kansas City, Kansas, crosses over I-70 and enters the loop in the southwest corner, rejoining I-70 and ending in Kansas City, Missouri in the southeast corner of the loop. I-670 is also signed as Alternate I-70. U.S. Route 71 is a highway that enters the loop in the southeast corner and leaves the loop with I-29 and I-35 in the northeast corner. Interstate 49 will eventually end at the southeast corner of the loop once Bruce Watkins Dr (which is currently US 71) is improved to freeway status. I-49 currently ends at I-435. U.S. Route 24 is a major city street which enters the loop in the northeast corner and follows I-35 and I-70 along the north side of the loop. US 24 is also known as Independence Ave/Blvd and provides a street-level connection to Independence, Missouri. U.S. Route 40 overlaps I-70 throughout the northern and eastern sections of the loop. U.S. Route 169 enters the loop in the northwest corner from the Broadway Bridge across the Missouri River, and joins I-70, continuing westward. Route 9 also provides access to the loop, ending at I-70 after crossing the Heart of America Bridge from North Kansas City. 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「Downtown freeway loop」の詳細全文を読む スポンサード リンク
