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). The entire circumference of the loop is just over .
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

History
Before the west side of the loop was built, there was a scenic road called Kersey Coates Drive in that place. There were many affluent homes that were built along the road, and stairs that led down from Case Park immediately to the east. When the loop was completed, the multi-lane Interstate cut further into the bluff and these homes were razed. The stairs leading down from Case Park were cut off halfway and still remain today, between exits 2W and 2X.
A March 2010 preliminary study of the Kansas City I-70 corridor made several innovative suggestions to relieve congestion in the downtown area. One proposal was to make the loop unidirectional, where the loop would essentially become a large
