Design and construction of Awatere road and rail bridges

The existing historic 2-storey 300m-long bridge carried both SIMT rail traffic and SH1 road traffic over the Awatere River on upper and lower decks respectively. Recent replacement of the traffic function of the existing bridge involved construction of a new traffic bridge over the river, a new rail over road bridge, and approximately 3km of approach highway, all constructed in a live road and rail traffic corridors. The new 10-span road bridge makes extensive use of modular precast components, and limits bearing and expansion joint location to the abutments. The new rail bridge was built off-line in two parts and slid into position from opposing sides of the track. The project successfully achieved technical, budget and programme objectives. Design and construction issues are discussed.
