How Australia Built the World's Widest Arch Bridge From Two Ends That Had to Meet in the Middle

Engineers grew Sydney Harbour Bridge's 503-metre arch from opposite shores, held only by cable. No support beneath it — and no way to fix a miss. The halves closed perfectly in 1930. A horseman then upstaged the Premier at the 1932 opening. Built by 1,400 Depression-era workers — the Iron Lung. #Bridge #CivilEngineering #Megaproject #AustralianHistory #Megastructure #HowItsBuilt #SydneyHarbourBridge DISCLAIMER _______________ This is not engineering advice.
