A Typical Decade of Bridge Construction

A recent decade of bridging, 1955–64, for motorways, State and main highways, roads and streets, based on official records for bridges over 25 ft in length.

New Zealand has constructed approximately 56,000 miles of roading in the form of motorways, State and main highways, county roads, and municipal streets. Capital investment amounts to some £500 million; and the annual expenditure on maintenance and improvement is approximately £28 million, of which an approximate £2 million is expended per year on bridging.
