Why Not Close The Road?

Indeed, if the road is failed, it should be closed off, correct? A failed road sounds like it might be a place you do not want people to drive, but it also sounds like exactly the kind of place people will ignore warning signs. We guess people should not operate any big vehicles on it. We are unaware of the weight capacity a failed road can handle. Honestly, we are still trying to picture how a failed road looks. It could not be a lot of potholes because, for whatever reason, cities tend to leave those open no matter how bad they get.
