Interstate 444 forms the eastern and southern half of the Inner Dispersal Loop (IDL) in central Tulsa. The urban loop is unsigned as it overlaps entirely with U.S. 75 and with U.S. 64/SH 51 on the south leg. Despite the unsigned status, the route may appear on some maps or GPS units.
Interstate 444 opened in three segments. The initial legs of the IDL opened in the early 1970s as spurs from Interstate 244. The southern section opened east from I-244 to 13th Street while the northern section ran south from I-244 to 7th Street.1 Several years transpired before the remainder of I-444, the southeast corner of the IDL, was completed. This took place in November 1981, with the Broken Arrow Expressway (SH 51) extending west to the IDL in March 1982.2
Exit numbers along both I-244 and I-444 were originally based upon the mileage of I-44 from the west end of the Turner Turnpike at Oklahoma City. Exit numbering along I-244 ranged upward from 89, while interchanges on the southern leg of I-444 were assigned Exits 94 A-D and those on the east leg were designated Exits 96 A-C.1 Exit numbers along the IDL were removed when the Oklahoma Department of Transportation (ODOT) made I-444 an unsigned route.3
