Nobody can understand whats happening after 10years of pot holes & unmaintained roads they seems to have started a major effort to repair/resurface  all the roads in the Amphoer . The Three most obvious are the roads from Ban Dung to Non Sawang, Thon Na Lab & Kut Du which have been in major need of repair since I can remember. Also they seem to have done minor repairs in many of the roads around town.
