Quote from the Chief of Traffic Police at Tung Tong police Station>>>
“The Phuket Provincial Highways Office is not resurfacing the road on the Kathu side of the hill because that section of the road falls under the responsibility of Kathu Municipality. They have no authority to freely resurface that section of the road.
Finally, just a little advice, the trick to driving over the hill safely after fresh rain is to drive slowly and keep left because the road will be slippery.”
LOL - yes, we know it's damn slippery and we are supposed to drive on the left. Seems crazy that the Patong side of the hill has just been resurfaced when it's the Kathu side that is the most dangerous especially near the bottom where it is the steepest and there are all those chunks of cement and debris to the inside line that force people to drive up in the middle of the road.
Then about halfway up just after a right-hand bend there's that enormous bump in the road (like there's a tree root or something like it trying to push through) that I have witnessed seeing a girl on a motorbike hit and cause her to go into the crash barrier.
So remember, if you have an accident on the way over on the Kathu side caused by the condition of the road it's the Kathu Municipality at fault...and the Patong Municipality if you've managed to pass the Chinese shrine and start the descent the other side on the nice new surface.
