Historical Background and Naming

Constructed between 1954 and 1958, Krung Thon Bridge was designed to relieve congestion on the Memorial Bridge and facilitate Bangkok’s westward expansion across the Chao Phraya River. The bridge’s name, “Krung Thon,” references Thonburi, Thailand’s former capital from 1767 to 1782, and reflects the enduring link between tradition and progress. Locals often refer to it as “Sang Hi Bridge,” after a nearby road (Wikipedia).

Architectural Features and Engineering

Krung Thon Bridge is a steel truss bridge measuring approximately 648.90 meters in length and 16.60 meters in width, accommodating four lanes of traffic and pedestrian walkways on both sides. Its seven spans rest on sturdy concrete piers, with the main span elevated 7.5 meters above the river to facilitate uninterrupted boat traffic.

The bridge’s light blue paint is both practical and iconic, protecting the steel structure from corrosion while giving it a distinctive appearance against the Bangkok skyline. Its design, featuring through-truss engineering and deep foundations, was advanced for its era and remains a testament to mid-century Thai engineering prowess (Trek Zone).
