| Abstract: | Three out of 22 river spans of the Tasman Bridge were destroyed by ship collision. The paper describes the method of debris survey in the deep water site conditions and the method of restoration determined therefrom. The unusual engineering tasks involved in the work included temporary repairs, demolition, major steel falsework, unusual vertical piling, the incorporation of a long steel span into the prestressed concrete bridge and erection techniques used. The whole bridge was widened concurrently with the restoration. |
