The Sydney Harbour Bridge spans the harbour at its narrowest between Dawes Point (south) and Milsons Point (north) — a riveted steel through-arch carrying road, rail and footways, with granite-faced concrete pylons. Ideas for a fixed crossing circulated through the nineteenth century (Francis Greenway is often cited as an early advocate under Macquarie); serious modern planning crystallised under engineer J. J. C. Bradfield, appointed to harbour-bridge and city-transit work from 1912. The Sydney Harbour Bridge Act 1922 authorised a high-level cantilever or arch; the construction contract went to Dorman, Long & Co. of Middlesbrough in 1924, with detailed structural design associated with Sir Ralph Freeman.
Approach and foundation work ran through the mid-1920s; the arch halves met in 1930. Premier Jack Lang officially opened the Bridge on 19 March 1932 — famously after New Guard member Francis de Groot slashed the ceremonial ribbon. Roughly eight years of construction employed thousands through the Depression; granite came from Moruya, steel from England and Australian mills. The Bridge remains a National Heritage–listed landmark and the everyday link Bradfield tied to the City Circle and northern lines.
The 2012 “80th anniversary” framing and any embedded video can stay as media; the paragraphs above are the place history the thin anniversary heading lacked.
