The Indian Nation turnpike is built to parkway-like design standards, omitting a center barrier and left-hand shoulders for a slightly mounded grassy median that is flush with the edge of the left lane in each direction. The turnpike's speed limit is 75 mph (121 km/h).
A two-axle vehicle pays $4.75 ($4.50 with Pikepass) to drive the full length of the Turnpike. *Toll has now increased to $5.50 (cash) for a full length trip as of 2013.
The route is one continuous four-lane limited access highway, but consists of two separately constructed sections. The 41.1-mile (66.1 km) northern section, which opened in 1966, is the portion between I-40/US 62/US 75 near Henryetta and US 69 south of McAlester. The southern extension opened in 1970, and is the 64.1-mile (103.2 km) segment from the US 69 junction to US 70/271 in Hugo.
