Hi all

We are looking to drive to Italy in September, can anyone please tell me if there is an extra cost to using the Gotthard Road Tunnel to cross from Switzerland to Italy? We have already paid for our Swiss vignette, and i'm reading on some websites that there is no additional payment for the Gotthard tunnel as we have the vignette....but on some other forums, some people are saying there is an additional charge, so it's all a bit confusing!
