Odds and Ends

Finland has a dense road network close to Russian border, and that place is nothing but a forest growing out of granite. To do anything in that place you'll have to cut and blast.
Obvious solutions are to have non-critical part of network as dirt-only roads and optimize pathing in a way that makes you do only enough blasting to supply rubble for leveling the rest of the way with embankment. Plus, utility roads probably have different safety standards, so they can turn harder and go up and down much more than what is usually acceptable for civilian transport.
