The Phanoen Thung road improvement project in the country’s largest national park, Kaeng Krachan in Phetchaburi province, is having its controversial design revised.

But as the public last month learned that the plan was to overhaul the entire route through the heart of Kaeng Krachan National Park, the fierce debate and arguments exploded on social media and triggered organised public events.
