The Sydney Harbor Bridge is steel through arch bridge and carries vehicular, pedestrian and rail traffic between the North Shore and the Sydney central business district. It took eight years to build this bridge from 1923 to 1932 and was open for public in 1932. This bridge is nicknamed as “The Coat Hanger” by the locals due to its arch based design. Designed by Dr JJC Bradfield, the crucial plans for the construction were entirely carried out by Ralph Freeman. The bridge is 134 meters in height and the pylons itself are 89 meters high. Moreover, this bridge is considered as the fourth longest single-span steel arch bridge in the world.
