- Abstract
The 1.8 km long F4 Viaduct between Granville and Parramatta was opened to traffic in July 1986 following a construction period of three years. It is the longest road bridge in NSW. The voided slab construction used proved to be very economical and readily adaptable to fit the varying road geometry requirements for the Viaduct. It also provided spans of sufficient length to cross seven roads and two railway lines, and minimised disruption to the many major underground utility services crossing the site. One unusual feature of the design was that short sections of the concrete superstructure at the ends of each set of continuous spans were initially omitted so as to allow access for the stressing jacks. These sections were subsequently completed in reinforced concrete. Also, for two particular spans, one over rail traffic and one over road traffic, where there was no clearance available for falsework to support the voided slab, a self-supporting composite steel box girder span was incorporated into the adjacent concrete voided slab spans as part of the continuous structure. This paper outlines various aspects of the development of this project and gives details of the design.
