The Indian Nation Turnpike, also designated State Highway 375 (SH-375), is a toll road in southeastern Oklahoma, United States, running between Hugo and Henryetta, Oklahoma, a distance of 105.2 miles (169.3 km). It is the longest tollway in the state.

Route description

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 80 mph (130 km/h).

A two-axle vehicle pays $7 ($6.20 with Pikepass or K-Tag) to drive the full length of the Turnpike.

Law enforcement along the Indian Nation Turnpike is provided by Oklahoma Highway Patrol Troop XC, a special troop assigned to the turnpike.

The only restaurant option along the entire turnpike is McDonald's near the McAlester exit.

History

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.

On December 2, 2014, the Oklahoma Turnpike Authority approved funds to reconstruct the Eufaula interchange, demolishing the Eufaula service plaza and relocating the toll Plaza to where the service plaza once stood. The interchange previously had the highest accident rate of all Oklahoma's turnpikes. The funds also went towards demolishing the Antlers service plaza. A new service plaza opened north of the McAlester interchange on December 19, 2014, containing a McDonald's.

The Indian Nation Turnpike originally bore no numbered designation. On August 2, 2021, the Oklahoma Transportation Commission unanimously approved a motion to apply the SH-375 designation to the turnpike. ODOT Director Tim Gatz stated in the Transportation Commission meeting that the numbering addition was primarily to aid in navigation using digital mapping and routing applications.
