My best guess is that you would want to use directional boring in that case. A
small hole every couple hundred meters, horizontal bore and duct pullback
between holes. No personal experience here other than watching it being done
for new pulls into existing developments. No need for digging up
yards/sidewalks/parking lots, just a bunch of potholes at the new junction
box locations and a single horizontal bore down the property line from the
street, intercepting each of the potholes.
