The section of Highway 118 between Chiang Mai and Mae Khachan was completed 2 years ago. The section between Mae Khachan and Mae Lao is currently under construction in small sections. There are currently 2 major issues: the interchange under construction at the junction of Highways 1 and 118 (traffic is required to take a very long and slow detour) while the highway from the earthquake zone to the junction (approx 7 km) is rough, slow and dusty.
The other major issue is about 8 km north westerly from the Charoen Resort. Long delays and lineups are to be expected, and the trip is extremely dusty.
