Hmm, perhaps. These days you can still get 30-50% from the EU but essentially only if it’s part of TEN-T or maybe some Green Deal related project.
The core network of major roads in Finland can be kept in a good shape, the issue is largely the thousands of kms of secondary and tertiary roads in the middle of nowhere that have too little traffic to be any sort of a maintenance priority, or to be eligible for EU funding. But you can’t really help it in a country that’s as sparsely populated as Finland outside major urban areas.
