Local gas utilities and water departments run either plastic lines or copper
lines with either a horizontal drill or an air powered torpedo that will run
under the road without digging, even where there is no road it is cheaper to
use than to dig up the whole line.

Unfortunately, this road is cut into a granite mountain side, so that type of
installation isn't an option.
