It is in the areas of the Thung Phaya Thai and Thanon Phetchaburi sub-districts which are the part of the Ratchathewi district in downtown Bangkok.
It was a bridge built to commemorate Prince Urubongs Rajsombhoj, one of the sons of King Chulalongkorn (Rama V), who died when he was a child.
Later on, the bridge and the canal were both demolished to make way for Phetchaburi road, but the name "Uruphong" still exists today.
[1] Between October 10th and November 7th, 2013, this intersection was used as a protest site for the Yingluck Shinawatra government by the Network of Students and People for Reform of Thailand (NSPRT).
These are separate organizations from the People’s Movement to Overthrow the Thaksin Regime (Pefot) and the Dharma Army.
