Travelled LNT to HX road yesterday on the public bus 7.5 hrs. Aside from a short stretch of bitumen around the midway point, road remains unsealed. Its two lanes wide of hard packed and dusty clay (ranging from mirror smooth to moderate rough) till about the last 25ks into Namtha. Here it narrows to single lane (two wheel ruts) with a dozen or so "mud holes" 2m - 20m long and a few patches of shaded damp clay. TDuk Chiang Rai.
