The posted speed limit is as high as 80 mph (130 km/h), making it possible to drive legally from Tulsa to downtown Oklahoma City in under 90 minutes.

In addition to the Oklahoma City and Tulsa entrance points on the turnpike, other interchanges are located in Wellston, Chandler, Stroud, Bristow, near Kellyville and Sapulpa.

Additional toll plazas, similar in design, were subsequently reconstructed at Chandler, Stroud, Kellyville, and Sapulpa.

A new interchange 11 miles (18 km) east of the western terminus was added at Hogback Road in Luther, and was opened in May 2011.

ODOT Director Tim Gatz stated in the Transportation Commission meeting that the numbering change was primarily to aid in navigation using digital mapping and routing applications.

That's common practice across the country, and you'll see that in many of the metropolitan areas, and that update will really be beneficial as far as everything from signage to how do you describe that route on a green-and-white sign."

Travelers exiting the turnpike westbound at Wellston or Luther, eastbound at Kellyville, as well as at the two termini do not receive any refund.

[9] Full service areas featuring McDonald's restaurants and Love's gas stations are located eastbound just east of Chandler and westbound near Stroud.

The Stroud facility is located in the median and previously served both eastbound and westbound traffic until June 2020 when the new Chandler service area opened.
