Redbournberry Bridge: dual composite design

The new $9.5 million Redbournberry Bridge spans the Hunter River near Singleton in NSW, alongside an existing 19th century historically significant iron truss bridge. The main spans consist of continuous steel composite trough girders. A limitation of conventional composite structures is the inefficiency of hogging sections. One solution to this problem is to provide a second composite slab at the bottom flange level, thus providing several advantages over more traditional methods. This paper will outline this and other innovative features of the design and construction of the main river spans and describe the preservation of the existing iron spans as a working part of the new bridge scheme.
