Rama III: a new landmark cable-stayed bridge reference in Thailand
Rama III bridge is a cable-stayed bridge with two H-shaped pylons, a 450-meter-long main span and 152 stay cables ranging from 40.5 to 233.7 meters long. The deck is quite large, hence the use of 48 to 109 strands of 15.7 m per cable.
Freyssinet Thailand, MajorProjects and our Industrial activity have designed, supplied and installed the whole stay cable system: cables, anchorages, dampers- and carried out the waterproofing and fatigue tests on full-scale specimens.
Congratulation to our teams who achieved amazing production cycles over the last months to complete the works on schedule, despite some initial delays due to Covid.
The bridge should be opened to traffic by the end of the year.
To optimise the future maintenance of the bridge, the client asked our sister company Sixense Group to supply equipment to monitor the structural health of the bridge.
