The construction of Rama III cable-stayed bridge in Bangkok has started!
Rama III bridge is a cable-stayed bridge with two H-shaped pylons, with a main span of 450m and 152 stay cables ranging from 40.5 to 233.7m long. The deck is quite large, hence the use of 48 to 109 strands of 15.7 m per cable.
Freyssinet Major Projects Department, together with Freyssinet Thailand, is designing, supplying and installing the stay cable system -cables, anchorages, dampers- and carrying out the waterproofing and fatigue tests on full-scale specimens.
Our Client also entrusted us with the supply and installation of the monitoring equipment that will monitor the structural health of the bridge in order to optimise its future maintenance.
The installation of the first pairs of cables started in May. To date, 32 out of 152 cables have been installed. The completion of the cable stays is scheduled for the first half of 2023.
