Palolo, Thank you very much for your advice. I had a trip by the new Alpha road from South Hawassa to Sodo. However, there are many sections my gpx different from the original small road and satellite photo which surprised me. It is understandable as the Asphalt road may chose different road profile. But the change on this road is too big, For avoiding messing up the area, I need to take longer time to finish this road.
