^Looking west from Exit 66 to Quaker Boulevard in Plainfield, July 2024.
Interstate 70 cuts east-west across Indiana's middle, linking Terre Haute, Indianapolis, and Richmond. Interstate 70 enters Indiana from Illinois just west of Terre Haute, heading east-northeast from St. Louis toward Indianapolis. In central Indiana, Interstate 70 reaches Indianapolis, becoming one of the two highways that are still allowed to penetrate to the core of the city. From Indianapolis, Interstate 70 continues nearly due east to Richmond, Indiana, and Columbus, Ohio. The border crossing into Ohio happens on the eastern edge of Richmond itself.
The exit list for Interstate 70 begins in the west and continues east, to coincide with the national mile numbering scheme.
