By: Jordan Tidwell CREEK COUNTY, Oklahoma - The Oklahoma Turnpike Authority is now beginning to phase out cash toll booths on turnpikes across the state. The John Kilpatrick Turnpike in Oklahoma City began using the new Plate Pay cashless system Sunday. State officials said the change is long overdue, and it will be much safer for those on the turnpikes. "Cashless tolling has been around for really in earnest the last 10 years, many, many other turnpike authorities, and turnpike operators across the country are utilizing cashless tolling today," state secretary of transportation Tim Gatz said. Green Country drivers can expect to see the change on the Creek Turnpike in 2022.
