It's worth using a route planner like via Michelin to look at where your going. It can estimate costs for being on a bike and also tells u what the toll roads charge along your route.
It can help decide if u want to use a toll or do the beaten track so to say.
There's even an app for it on your phone.
I'd also consider an off line map app on your phone. U can download it before u go and then u don't need data whilst your away (or if not available).
Austria has a charge for using the motorways though. It's called a vignette. U can buy them before u go online and they post them to u. Sometimes easier just in case.
