I-44 was originally signed in 1958 as an Interstate designation of the

linking Tulsa and the Missouri state line southwest of Joplin, along with the US 66 bypass in Tulsa that linked that city with the two turnpikes and the continued four-lane highway from the Missouri border to an interchange with US 71 south of Joplin previously designated as US 166.

(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

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
