In the U.S. state of Indiana, Interstate 80 consists entirely of the following two routes:

• The Borman Expressway from the Illinois state line to Lake Station running concurrently with Interstate 94, U.S. Route 6, and U.S. Route 41.
• The Indiana Toll Road from Lake Station to the Ohio state line running concurrently with Interstate 90.

I-80 also runs concurrent with another Interstate Highway throughout its entire course in Indiana. The western portion is cosigned with Interstate 94 in the vicinity of Gary; the rest of the route is cosigned with Interstate 90. This is the only instance of an Interstate running concurrent with another on the entire length of the Interstate in any given state.
