I'm heading to Rimini from Bosnia and Hercegovina and I know how much money I need for road toll in Croatia and Slovenia, but it's bit confusing when I look at Italy road tolls.

I'll be entering Italy from Slovenia place called Nova Gorica or Gorizia, and by my calculation's I will need about 20 euros in one direction, so 40 euros in both direction.

I'm I right about this, and if I'm not can someone help me and explain how can I calculate road toll in Italy, for this road section.
