Drivers on the Kansas Turnpike will pay more beginning Oct. 1.

The state announced Wednesday that tolls on the turnpike will increase about 5% for passenger vehicles with a K-TAG pass. Commercial vehicles with a K-TAG may see an increase because electronic fares will be rounded to the nearest nickel.

Fees for passenger vehicles paying cash will increase about 12.5%, while commercial vehicles paying cash will see a 10% increase. All cash fares will be rounded to the nearest quarter.

The turnpike authority says about 40% of customers pay cash, while 60% use an electronic system such as K-TAG.

State officials said the turnpike system is financially sound but the toll increases are needed to pay for preservation and modernization projects without issuing new debt.
