Texas/Oklahoma
Missouri (PART 1/PART 2)
Most of I-44 in Oklahoma is a toll road.
I-244 in Tulsa has its own dispersal loop, the unsigned I-444 around downtown. While some maps show the I-444 marker, the freeway is signed as US 64, US 75 and OK 51.
What was once I-244 around St. Louis is part of that city's I-255/I-270 beltway.
