Rama IX Bridge is a bridge in Bangkok, Thailand over the Chao Phraya River. It connects the Yan Nawa District to Rat Burana District as a part of the Dao Khanong – Port Section of Chalerm Maha Nakhon Expressway.[1][2][3]
The bridge was named in the honor of King Bhumibol Adulyadej's 60th birthday. The opening date coincides with the king's birthday. It was the first cable-stayed bridge in Thailand[1] and had the second-longest cable-stayed span in the world when it opened in 1987.[4][5]
The original colour scheme, with white pylons and black cables, was replaced with an all yellow scheme representing the king in 2006.[6][7]
Bridge structure

The steel superstructure includes the bridge, rigged mast, and cable. The main span of the bridge, which is stretched between two poles, has a length of 450 meters. The main span is a trapezoid 33 meters wide. The bridge has a walkway along its side. The bridge has two main pylons 3 x 4.50 meters. This serves to hold the tension of the cable and weight into the pylon pier. The 121 – 167 mm diameter cables consist of many small wires wound together. The cables vary in length from 50 to 223 meters can absorb the tension for 1,500–3,000 tons.[8]
