Nan Tien Temple Bridge Over Princess Highway

The 113m long Nan-Tien project involved the design of a new pedestrian footbridge over Princes Motorway near Wollongong, NSW. To eliminate the pier between the two carriageways, the large center span required the Super-T girders to be made continuous and integral with the piers. This presented various challenges for the design and construction of the bridge, the temporary works and the approval process.

The solution was to first construct the substructure and erect the girders on a temporary bracket system stressed against the piers to transfer the load. The brackets had to support the girders for several weeks until the superstructure was finalized. Secondly, cast the in-situ topping slab in the middle of the main span. Finally, cast the in-situ infill pours at each pier head to connect the two girder spans and the pier.

Once again Cardno called upon Latter Rain’s experience to contribute to the development of the temporary works and detailing this non-typical bridge.
