Cheers for the State of Colorado. They have found a great way to save money and rip off the traveller. Fire the Toll Road Collectors, don't collect tolls for actual usage, don't tell the travelling public and bill them through car rental companies for every day they rent a vehicle.
I travelled from Denver Intl Airport to 76, a short distance. The toll both is closed. The toll is stated as $2.50 for about 5 miles. Two months later I get a bill from PlatePass for $12.50 for use of the toll road for the entire week.
Now warning from Hertz, no public notice. Out right theft!
Stay off E-470, or better yet, don't visit Colorado!
