Not sure if FL48 still exists or not. From I-75, both directions have signs for only CR48, and the entire E/W portion (where signed) that is FL48 in the HB is CR48 in the field. The N/S portion did have one FL48 sign in each direction, and northbound indicated a left turn, but the first westbound sign was CR48.
I did not see any FL48 signs on US301, either.
