When you are travelling from Pascoe Vale through to Frankston you are travelling on both of the toll systems Citilink and Eastlink. When you are travelling major distances like the ones you have mentioned above you would be paying the maximum capped rate for both. This would mean a cost of $7.33 for Citilink and $5.57 for Eastlink. This would make a total cost of a one way trip at $12.90. This would be doubled for a return trip.
