The arch of the Sydney Harbour Bridge was built in two halves cantilevering from each shore and tying each half back by steel cables that were anchored into U-shaped tunnels excavated into the sandstone rock. Construction of the two halves of the arch began late in 1928, and the two halves were properly joined around 10pm on 19 August 1930.
