History

Phahonyothin Road was originally called "Prachathipat Road" (Thai: ถนนประชาธิปัตย์, Thanon Prachathipat, literally "Democrat Road"), and reached just 22km (14miles) to Don Mueang. In 1938, Field Marshal Plaek Phibunsongkhram had the road extended from Don Mueang, through Bang Pa-In, Ayutthaya, Saraburi, Lopburi, and Singburi, making it 162km (101miles) long. The newly lengthened road was renamed Phahonyothin Road, in honor of General Phraya Phahol Pholphayuhasena (formerly Phot Phahonyothin), the second Prime Minister of Thailand and one of the heads of the 1932 revolution.[1]

Route

In Bangkok, Phahonyothin Road originates at the northeast corner of Victory Monument on the periphery of Ratchathewi and Phaya Thai districts, then crosses Chatuchak, Bang Khen, Don Mueang, and Sai Mai districts before continuing into Pathum Thani Province, and on through Ayutthaya, Saraburi, Lopburi, Nakhon Sawan, Chainat, again through Nakhon Sawan, Kamphaeng Phet, Tak, Lampang, Phayao and finally Chiang Rai, ending in Mae Sai district, where it connects to Tachileik in Myanmar.
