Only notable attack to rus territory that I was aware of was Millerovo airfield in the early days , there are some alleged videos of that which was a missile strike.
As far as bridges go I am not at all sure why Ukraine did not drop the Antonovoski bridge over the dnieper
If they had the situation would look different in the south. It can be by intention to dissipate russian forces, or just because the bridge is too damn big n tough. They did blow plenty of other bridges in the Kherson area on the first 2 days , notably the one where the trooper gave his life to manually detonate. That whole area is full of tributaries and loops of the main river.
I am not so sure they will be so reticent if orc forces reach the dnieper crossings in more central areas
