OP experienced bad roads recently on the east ...double the problem and more !
We travelled from Susa going near Turin and south to Cuneo on Non-toll roads...Rutted Pot-hold Traffic after that is was M Ways always. As I posted earlier we spent a total of 117Euros on Italian Tolls including Sicily -but not including Ferries)
Well worth it
When planning to go via Genoa remember one of the main bridges collapsed late summer so beware of the satnav but there will be diversions signed
