Hello, my wife and I are planning a multi-country trip (to take place at some point when covid restrictions lift) that includes Italy, solely for going to Venice. We plan to rent a car in Zurich, do some travels through southern Germany, stay in Austria for a night and then head down to Venice. Toll roads are ok but would be nice to know how much to expect to pay. The rental car is through Europcar, and per the specific rental office's Terms & Conditions, travel to Germany/Austria/Italy is allowed with the car. I'm aware of the infamous Italian ZTLs... Though our route appears to be exclusively highway. Here are the two routes below, I'd appreciate feedback on if 1. we'd encounter any issues along these routes 2. if there are any restricted parts of these routes 3. about how much in toll fees it'd cost 4. if we happen to be missing any ZTLs along these routes (we don't appear to be going through any city centers at all)
Route 1 Austria to Venice: A22/E45 > A4/E70 > A57 > SR11
Route 2 Venice to Tasch, CH: SR11 > A57 > A4/E70 > A8 > A26/E62 > Reno navetta Sempione train
