The New Zealand Concrete Society's 1983 award for excellence in prestressed concrete was given to the 3 Mangaweka rail deviation bridges: the South Rangitikei Bridge with a prestressed concrete box girder deck 315M long with a maximum span of 56M supported on twin piers rising 76M above the river bed; the method of construction adopted used a self launching steel falsework system. The North Rangitikei and Kawhatan Bridges which had the same design: a prestressed concrete box girder spanning 110M across the gorge and rising 70M above the river bed. The bridges have shorter end spans giving a total length of 182M; construction was by the cantilever method using a mobile formwork system and cast in place concrete. The structural depth varies from 3M at midspan to 7.75M at the main piers. Details are given of the costs and materials. (TRRL)
