They are actually gravel roads that acted as distance markers for the old bomb tests they used to carry out back in the 60's and 70's, spaced out from the target zone. From my understanding they used to do a lot of tests related to how far out damage occurred from various ordnance being detonated, so they'd place the test sensors along those roads for easy access but being able to know exactly how far things were without measuring every time.
