The Tamwe Flyover:
DYWIDAG Post-Tensioning Systems for 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 1,477m, 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
75t.
The viaduct’s 11.2m cantilever pier heads
were post-tensioned using DYWIDAG Strand
Tendons. In total, Utracon supplied and
installed 114 Type 19-0.6" DYWIDAG Strand
Tendons and 12 Type 37-0.6" DYWIDAG
Strand Tendons including anchorages and
56
accessories with a total strand tonnage of
22.3t. 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.
Thanks to the close cooperation with the
General Contractor, Utracon was able to
successfully install the DYWIDAG Strand Post-
Tensioning Systems despite the congested
reinforcement with small interstices.
