Can anyone confirm that this route (hwy 2E) is now paved as it goes thru Phongsal Province via Muong Khua? I'll be returning from Northern Vietnam to Chiang Rai via this crossing and am worried about clay roads during the raining season. The lastest GT RIDER MAP (2012) shows it as a dirt road, but someone I met in Laos said it is now paved. HELP!!
