it was built from a scratch.. the successive Somalia/Somaliland govts the past 5 decades did not build shit in Awdal. not sure about the cost but it must be damn costly looking at the nature of the hilly Borama town and its rocky roads.
this is probably how it looked like before paving it..
there is another one being built connecting Borama town to Dilla town its ongoing for coupla years now and almost completed.
