Interstate 235 runs along the east side of downtown Oklahoma City. (There being only so many three-digit numbers, you'll see it again in Wichita and Des Moines.) It stretches from the I-35/I-40 junction north to I-44; the freeway continues north from I-44 but is not considered part of 235.
Officially, this section of 235 runs a bit less than 5.5 miles, making it one of the shorter Interstates around. Similarly, Carnival of the Vanities #235 is one of the shorter Carnivals around; still, like an Interstate spur, it's a handy thing to have.
