(AASHTO) rejected the request. At the time the I-44 designation was assigned in Oklahoma in the 1950s, Oklahoma signed the milemarkers west to east starting at Turner Turnpike's Oklahoma City terminus at the I-44/I-35 interchange (near Edmond). I-44 was extended in 1982 southwest of Oklahoma City along the existing

, thus raising the milemarkers by about 100. The addition of the new section was unusual in that it is a more north–south segment and did not directly connect to the previous western end at I-35. It now extends south of I-40, an exception to the Interstate numbering rules and its end point does not connect to another Interstate Highway. What was once
