Because they are two separate networks with roughly the same geographical
scope. How would you distinguish Interstate 30 from US Route 30, which are
hundreds of miles away from each other?

Some Interstate highways do not cross state lines themselves, but the idea
behind the name is that the network as a whole does. Regardless, that's
just the name for our national freeway network.
