At least you have the poles. When I first moved to Ohio in the early 90's and was caught in a snowstorm on the outerbelt on the way home from work and there were no signs or light poles yet and snow driften across and wasn;t yet plowed. There was a spot where you couldn't tell where the road was and just drove by feel, if you went off the shoulder the side of the truck would sink into the grass so I knew I was off the road and owuld turn the other way a bit.
