Destroying bridges, rail, etc would be a huge mistake (beside maybe those leading west to NATO), as the current logistic challenges underscore. The initial blitz did target radars and airports (strategic infrastructure) to try to get air superiority, after which many more options become available. But that didn't play out. We're seeing now a transition to siege tactics; surround and generally make life miserable.
