well that situation was what was shown in the documentary. i can't say how common that is, but given the cost and notorious lack of funds i think it is more common than we like. i could be wrong though. we could use google streetview to check.

as for alternative roads, that really depends. generally from my experience between two neighboring villages there tends to be only one road, unless you want to make a big detour. sometimes alternate roads exist when and old main road is replaced with a new one on a different route.
