We have seen this happen to roads after an earthquake or some act of mother nature, but what if this happened with no explanation? Worse yet, what if it happened while you were driving on it! This highway in Arizona had a long stretch of it literally crack apart on it’s own. Pretty dangerous too, because it left some deep holes in the road that would of caused very serious accidents if anyone was around. Experts thought it was a landslide, but there was no evidence for that either. Take a look for yourself and check the gallery after the jump.
