The Indiana portion of I-65 begins in Jeffersonville after crossing the Ohio River and travels mainly north, passing just west of Columbus prior to reaching the Indianapolis metro area.

Northwest of there, in west-central Jasper County, the route again curves more northward as it approaches the Calumet Region. Shortly after passing a major junction with I-80 and I-94, I-65 reaches its northern national terminus in Gary at US Highway 12/US Highway 20 after an interchange on I-90.
