How do they decide the way mountain roads twist and turn?
In: 200
Road builder (off-highway) from British Columbia here. Our clients basically draw a line on the satellite images of where they want the road, then another company will walk it and ribbon off a trail to follow, then we go out, clear the right of way, and build the road. If it is steep terrain it gets designed by engineers but other than that we basically just figure it out.
