Sub and super structure standardisation

In this paper the main types of bridges designed and constructed by the Country Roads Board are discussed. Very few bridges require pier heights in excess of 15m or span lengths greater than 50m. Construction is generally of reinforced concrete substructures and reinforced and prestressed concrete superstructures. The use of steel beams and girders is limited as fabrication and maintenance costs of steelwork are not usually competitive with reinforced and prestressed concrete. Standard type structures of reinforced concrete have general application for the smaller type bridges in common use and standard superstructure members comprising reinforced and prestressed concrete slabs and beams are widely used. Bridge bearings, deck joints and barrier railing are also of standard types.
