No worries about Croatian. :)
I added back the access road before the toll booth. I added access=no to the northern part of the highway exit.

 This part of the exit was never open to traffic due to ongoing excavations nearby and alternating traffic and so on. I live nearby and I'll check the situation there again soon.

On the southern side, near the gas station it looks like there won't be any more construction of roads for now. So those might need to be "planned" instead of "in construction". There is no material deposited to construct the road on for now. I'll have a look also, haven't noticed any signs of that, but I also wasn't aware of these plans. It is not that important for now. Cheers
