The Cherokee Turnpike is a toll road in eastern Oklahoma. Opened in 1991, the route is a four-lane tollway carrying US-412 from east of Kansas, Oklahoma to east of Chouteau, and has a total length of 32.8 miles (52.8 km) and a speed limit of 75 mph (121 km/h). An alternate route, US-412 Alternate, provides a free but not controlled-access route through the towns bypassed by the Turnpike with only a 55 mph (89 km/h) speed limit.
The turnpike begins by branching off US-412 east of the Grand River in Mayes County. The turnpike carries US-412 for its entire length; the old alignment of US-412, which was also at one time State Highway 33, is now US-412 Alternate. The Cherokee Turnpike runs within a close distance of US-412 Alternate for its entire length. The turnpike generally varies only a few degrees from true east–west throughout its entire route.
The turnpike's first exit is a diamond interchange with State Highway 82 just south of Locust Grove. From this point, the road travels 11 miles (18 km) without another exit. During this interval, the highway crosses from Mayes into Delaware County. Just after crossing the county line, the Cherokee has its second exit, again meeting US-412 Alternate southeast of Rose. This second exit is a partial cloverleaf with loop ramps in the northwest, northeast, and southwest quadrants.
