Following the Boworadet Rebellion in October 1933, the government of Phraya Phahonphonphayuhasena proposed the construction of a highway linking central Bangkok with Don Mueang Airfield to strengthen its control over the facility. Construction began in March 1934 and was completed in July of the same year. The road was originally named "Prachathipat Road" (, Thanon Prachathipat), spanning a distance of 22 km.

In 1938, Prime Minister Plaek Phibunsongkhram ordered the extension of the road from Don Mueang through Bang Pa-in, Ayutthaya, Saraburi, Lopburi, and Sing Buri, bringing its total length to 162 km. The extended road was renamed Phahonyothin Road in honor of Phraya Phahonphonphayuhasena (personal name Phot Phahonyothin), the second prime minister of Thailand and one of the leaders of the 1932 Siamese revolution.
