- dragonwriter 9y agoOver time, most cost of a road is maintenance cost, not initial construction. While this probably isn't linear with use, it does scale with use, so that lower use means lower maintenance cost. The cost of a single lane road supporting current usage levels is not an individual less quantum unit of road cost.
