The Tamwe Flyover will be Yangon’s longest Viaduct

In Yangon (Rangoon) in southern Myanmar, several viaducts are being built that will enhance traffic flow. One of these viaducts is the Tamwe Bridge that will connect three of the city's most congested roads by a Y shaped intersection.

At a length of 1,477 m, the Tamwe Flyover will be Yangon's longest viaduct. The flyover has a foundation consisting of reinforced concrete bored piles and is designed for loads of up to 75 t.

11.2 m cantilever pier heads

The viaduct's 11.2 m cantilever pier heads were post-tensioned using strand tendons. In total, Utracon supplied and installed 126 strand tendons including anchorages and accessories with a total strand tonnage of 22.3 t.

To make the construction of the long cantilevering elements easier, Utracon also suggested a suitable construction method and solutions for the formwork system that was used. Despite the congested reinforcement with small interstices, it was possible to successfully install the strand post-tensioning systems.
