I know UTHSCSA is, but I'm just pretty sure that University Hospital is. There is a 30-06 sign as you transistion from the hospital to the school.
Technically, you don't have to go outside to go from the school to the hospital.
I guess, if it is a school, why bother with the 30.06 signs? I'm not carrying there, but it is interesting to see the reason for the madness. . . . or the madness for the reason.
