 Tulsa mayor Rodger Randle 's committee on the Creek Turnpike submitted a report to OTA on April 13 , 1989 , requesting that the agency make 47 changes to the turnpike . Among the changes proposed by the city was a shift in the route of 100 feet ( 30 m ) to the north between Yale Avenue and Sheridan Road to accommodate a greenway along both sides of the turnpike . The committee also recommended wider overpasses to accommodate future expansion of surface streets such as Delaware Avenue , moving the mainline toll plaza farther east to minimize impact on the surrounding area , and better compliance with local flood prevention ordinances . In addition , the report suggested better pedestrian access , including pedestrian bridges on both sides of the Arkansas River and near Hunter Park , and various sidewalks and pedestrian tunnels .
