Phahonyothin Road (Thai: ถนนพหลโยธิน, RTGSThanon Phahon Yothin, pronounced [tʰā.nǒn pʰā.hǒn jōː.tʰīn]) or Thailand Route 1 is a major road in Bangkok and one of the four major highways in Thailand, which include Mittraphap Road (Route 2), Sukhumvit Road (Route 3), and Phet Kasem Road (Route 4). It begins at Victory Monument in Bangkok and runs north to the Burmese border, with a total length of 1,005 km (624 mi).


Mae Sai Pass

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.[1]
