History
Phahonyothin Road was originally called Prachathipatai Road (Thai: ถนนประชาธิปไตย, Thanon Prachathipatai, literally "Democracy Road"), and reached just 22 km (14 mi) 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 162 km (101 mi) 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.
Route
In Bangkok, Phahonyothin Road originates in Ratchathewi district and crosses Phaya Thai, Chatuchak, Bang Khen, and Don Mueang 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.
