Just ridden Mae Sariang to Mae Hong Song. A few Km from Mae Sariang there is 3 or 4Km of road works, some one lane with traffic control. Hard packed soil that has been watered on shallow inclines. Fortunately it is surface water only not deep mud. Taking it slowly, no slips and the bike is still fairly clean. There were a number of other road work signs further on but all these had been tarred and completed.
