I-75 connects Canada with the southern tip of Florida. The Alligator Alley section west of Ft. Lauderdale is due east/west.
I-375 in Tampa apparently still exists, but it's so small that maps don't always bother labelling it.
I-475 around Macon is shorter than the main route I-75. The only other examples of this phenonenon (to my knowledge) are I-10 which has two, both in Louisiana; and I-64, which has two of its own in the Hampton Roads area of Virginia.
