Gilberton Swing Bridge

Working in partnership with the Council, heritage advisor and engineering consultants OPUS, Civil Tech Pty Ltd undertook the replacement of the 55m long heritage listed swing bridge in late 2017. The existing plywood and steel bridge was carefully demolished and replaced with a new structure comprising of a light-weight plastic decking on a CFT substructure, hung from two 48mm steel cables. Civil Tech undertook design and construction of the composite pier-and-pad footings at each end, encompassing over 25m3 reinforced concrete in each abutment.

The Walkerville side abutment was particularly challenging, being founded nearly 4m below adjacent road level, on a steep riverside embankment. Civil Tech worked closely with the other stakeholders to resolve the finer details of fencing, balustrades and stairs, delivering the project in time for a formal public opening in early January 2018.
