Today in Transportation History – 1912: The Last Chaloem Bridge in the Series Opens

In Siam (now known as Thailand), the Chaloem Sawan 58 Bridge made its formal debut in the capital city of Bangkok. The bridge, crossing the northern end of a manmade moat called Khlong Khu Mueang Doem in Bangkok’s present-day Phra Nakhon District, was opened by King Vajiravudh (Rama VI) on the second anniversary of the death of his father and immediate predecessor King Chulalongkorn (Rama V).

The bridge had the distinction of being the last of 17 bridges that were opened annually in Bangkok by the Siamese royal family and known collectively as the Chaloem Bridges Series; the first of the structures, the Chaloem Sri 42 Bridge, had been inaugurated by King Rama V in September 1895.

After opening the Chaloem Sawan 58 Bridge in honor of his late father, King Rama VI initiated a new series of bridges likewise constructed and opened on a yearly basis. This sequence, known as the Charoen Bridges Series, continued until the dedication of the Charoen Sawad 36 Bridge in December 1916. King Rama VI then decided that enough bridges had been built in Bangkok. The Chaloem Sawan 58 Bridge remained in service until being dismantled in 1971 to make way for the new Somdet Phra Pinklao Bridge at that location.
