The toll road is not a state highway, but is instead maintained by the E-470 Public Highway Authority, which is controlled by a governing board of ten elected officials, three from each county and one from Aurora. Construction and operation involves no state or federal funding or taxes.
The toll rate on E-470, roughly 33 cents per mile, is one of the highest rates of any toll road in the United States
