History

Phahonyothin Road was originally called Prachathipatai Road, and reached just 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 long. The newly lengthened road was renamed Phahonyothin Road, in honor of General Phraya Phahol Pholphayuhasena, the second Prime Minister of Thailand and one of the heads of the 1932 revolution.
