First job was to check out the San Pa Tong bypass, a Godsend which will avoid the single lane, R 108 bottle neck. through San Pa Tong. Dual carriageway, its fantastic.
Once we'd researched it, we took some back roads (& dirt!) south to R 1013. Checking R 1013 west of Mae Wiang, the only road work section left is at co-ords:
N18.68115
E98.62657
Its 500 meters long, on a hill, hard packed, graded, smooth sand. The other half of the road is concreted, only half (on lane) is currently usable. Looks like in a couple of weeks, the whole of R 1013 to the R 1284 junction, will be sealed road.
Westwards on R 1013 to the junction south on R 1284, south on R 1284, the only unsealed road is road works at co-ords:
N18.60151
E98.51409
Again, hard packed sand and gravel, this time for about 1km but on mostly a flat surface (no gradient).
