Interstate 444 forms the eastern and southern leg of the Inner Dispersal Loop (IDL) in central Tulsa. The urban loop is unsigned as it shares alignments with U.S. 75 throughout and U.S. 64 & Oklahoma 51 on the east-west portion. Despite the unsigned status, the route may appear on some maps or GPS units.
$7.2 million in construction rehabilitates four bridges at the southeast corner of the IDL, where the Broken Arrow Expressway ties in from the southeast. Work started in January 2017 and runs through early 2018.4
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 Interstates 244 and 444 were originally based upon the I-44 mileage 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 94A-D and those on the east leg designated Exits 96A-C.1 Exit numbers along the IDL were removed when ODOT made I-444 an unsigned route.3
