From the ancient city of Kamphaengphet through the area of Phra Krua District, Khiri Mat District, the ancient city of Sukhothai, Sawankhalok District, Muang Bang Klang, to the ancient city of Si Satchanalai, the clay compact was found the clay compact with the canals along the two sides. In archeology, also it is still argued it should be the road, irrigation canal, or both.

The people who have seen this street for generations do not know what is its beginning and end. The story was created to describe. It was said that this was from the power of the supernatural word of Phra Ruang. He just used his feet to sweep and it became a road. Some said that it was a route for him to run after the lite. Some said that it was a route to find fighting cocks.

In 1907, Crown Prince Maha Vajiravudh (later King Rama VI) had been exploring Phra Raung Road, from Kamphaeng Phet to Si Satchanalai. Then he wrote a book on the occasion of his visit called "Visiting the City of Phra Ruang"- This was the report of the survey of the city and the early traveling book of this ancient city.
