What is the cost of the toll roads from Iowa To Phoenix Arizona?

The Kansas Turnpike is the only toll road on which you will travel. If you enter Kansas on I-35 from Iowa and exit at the southern terminus of the turnpike, your cost will be $8.25.

If yours is a roundtrip, you can purchase a K-Tag for $15 and get $10 in toll credits. You must purchase the K-Tag with a credit card and establish an account, which you can cancel once your trip in complete. If you do not cancel, your card will be charged on a monthly basis.
