RESTORATION OF THE TASMAN BRIDGE

The demolition of two 80 M pile and pier supports by an ore carrier, and the subsequent collapse of three spans left a 128 M gap in the Tasman Bridge and destroyed the pattern of travel in Hobart. Reconstruction was hampered by the sunken ship and wreckage of the bridge superstructure in depths of 20 to 40 M of water with poor visibility. Accurate location was only possible with specially developed sonar equipment. The method of restoration chosen was to build an 85 M steel box girder from pier 17 to 19 with a new pier at the site of pier 19, and a 43 M prestressed concrete span from pier 19 to 20. Pier 18 was too difficult to replace and the shafts of piers 17 and 20 require reconstruction. The replacement spans are to be floated down river, and lifted into position by derrick cranes. The complete bridge is to be widened from four to five traffic lanes at the same time as the restoration. /TRRL/
