Municipal type bridges: new developments
Municipal type bridges need to be as economical as possible, designed to withstand the elements and modern traffic with minimum maintenance requirements, and combining simple standardized pre designed elements which minimize the amount of design and drafting work required of the municipal engineer. In addition new processes are required, or improvements to old processes, which will prolong the life of the many old deteriorated timber bridges, enabling them to carry the present day heavier traffic until funds can be provided for their replacement. Amongst the new bridge and culvert designs used by the CRB which meet these requirements to a greater or lesser degree are 'spir-l-ok' or 'hel cor'; large rc pipes; slab linked large rc box culverts; 'fabriform' jacketting of timber piles; and reinforced concrete overlay of timber bridge decks.
