Highway, Yunan Province: The roads in China are a breath taking work of engineering. Entering from Laos, where the road is so muddy our bus was often going up hills sideways to avoid bogging, the contrast was stark. In China, mountains and valleys are no obstical, the road continues straight, tunnelling through the mountains and bridging over valleys, for kilometers, if that’s what it takes. The roadside reading “Descent for next 54km” is probably not in existence anywhere else in the world. They have special emergency breaking areas for trucks when breakpads get too hot on the constantly angled declines.
