BURDEKIN RIVER BRIDGE – AUSTRALIA
BURDEKIN RIVER BRIDGE – AUSTRALIA
The Burdekin Bridge (known as the Silver Link) spans the Burdekin River between the towns of Ayr and Home Hill, Queensland, Australia. Located on the Bruce Highway which is part of Highway 1, it is an important link in the national road network.
It is a road-rail bridge which provides a high flood immunity link between north and south Queensland. The Bridge was completed in 1957. Construction began 10 years earlier in 1947.
Early 2013, the road support structures were coated with ZINGA, specified with a class Sa 2½ abrasive blast clean, followed by 2 coats of ZINGA to an average dry film thickness of 180 μm.
The coating system for the rail support structure required a decorative silver finish, and the coating system was therefore as described but incorporated a coat of ALU ZM.
A dry film thickness of 40 μm was specified.
System:
ZINGA 2 x 90 µm DFT
or
ZINGA 2 x 60 µm DFT
Alu ZM 1 x 40 µm DFT
