In the U.S. state of Indiana, Interstate 70 (I-70) travels east–west across the state passing through the capital of Indianapolis. I-70 crosses from Illinois into Indiana near Terre Haute and departs into Ohio at Richmond. It covers 156.60 miles (252.02 km) in Indiana, paralleling U.S. Route 40 (US 40), the old National Road.
The Indiana portion of I-70 begins at the Illinois state line west of Terre Haute. Heading east, I-70 crosses the Wabash River soon after entering the state. US 40 travels concurrent with I-70 briefly before breaking off and traveling north of the interstate into the center of the city. The interstate crosses through the south side of Terre Haute, where it has an interchange with US 41/US 150. Just outside the city to the east, I-70 passes near Terre Haute International Airport before continuing onward to the east-northeast through rural lands towards Indianapolis. This stretch of I-70 does not have any interchanges with any significant cities until it reaches the Indianapolis metropolitan area, but it does pass within proximity of Greencastle.
