Pin Klao was the name of the last but one deputy king (maha uparat) in Thai history, who was the younger brother of King Mongkut (Rama IV) and whose palace was in the area where Thammasat University stands today. When a bridge was built across the Chao Phraya River near the place in 1973, it was named Pin Klao in memory of the late deputy king.

Now the area on the western side of the river has become one of the most newly developed areas in Bangkok with department stores, many restaurants and nightlife establishments. The wide road starting from the bridge leads to such tourist spots as Samphran Elephant Ground & Zoo, the Rose Garden, Nakhon Pathom, Phuttha Monthon, and Thai Human Imagery Museum. Along both sides of the road are numerous fashionable residences.
