Phahonyothin Road (Highway 1)
A 1,005 km road born from a failed coup — it starts at Victory Monument and doesn't stop until Myanmar.

Built in 1934 so the Thai government could assert physical control over Don Mueang Airfield after the Boworadet Rebellion. Extended north in 1938 and renamed for Phraya Phahonphonphayuhasena — the second prime minister of Thailand and a leader of the 1932 revolution that ended absolute monarchy. The road's origin and its name are both political acts frozen in asphalt.
What to look for
- The northeast corner of Victory Monument, where Highway 1 officially begins
- Highway 1 markers running north through Chatuchak toward Don Mueang — the airfield the road was originally built to reach
- District boundary signs: the road doubles as a legal dividing line between sub-districts in Ratchathewi and Phaya Thai
BTS Victory Monument station drops you at the starting point; heading north on foot reaches Chatuchak district within minutes.
