 In 1982, as part of Oklahoma's "Diamond Jubilee", I-44's western terminus was moved from the I-35/I-44 junction near Edmond, Oklahoma to the Texas/Oklahoma state-line via the Belle Isle Freeway (part of the recently designated I-240 connecting the former I-440 with I-35); I-240, the H.E.Bailey Turnpike; and the turnpike connector road on the eastern edge of Lawton, Oklahoma.While the I-440 number was dropped in 1975, it is available if needed in the future.
