Interstate 444 (I-444) is an unsigned auxiliary route of the Interstate Highway System, with both ends at I-244 in downtown Tulsa in the US state of Oklahoma. It makes up the eastern and southern sections on the square-shaped Inner Dispersal Loop.
It is signed as U.S Highway 75 (US-75), with the first half of the highway also being signed as US-64 and State Highway 51 (SH-51). And I-444 doesn’t connect to the parent route (I-44).
I-244 and I-444 initially used exit numbers in the 90s range, based on the milemarkers for I-44 in the Tulsa area and where they diverged. I-444 had four exits that were numbered 94A–94D until the highway designation became unsigned in 1995.[2] The exit numbers were removed, leaving only the letter suffixes before later becoming unmarked.[2]
Exit numbers and mileposts no longer exist (see History section above for explanation of exit numbers). The entire route is in Tulsa, Tulsa County.
