The downtown loop, also nicknamed the "Alphabet Loop", is a complex layout of highways in downtown Kansas City, Missouri involving 23 exits, four Interstate Highways, four U.S. Highways and numerous city streets. 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).

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.
