Sydney Harbour Bridge row overshadows anniversary celebrations

The 75th anniversary of Australia's greatest engineering achievement the Sydney Harbour Bridge is being overshadowed over claims from UK consultant Hyder, that Englishman Ralph Freeman designed the structure.
'The row goes back a long time. Australian John Bradfield did the concept design but it was Sir Douglas Fox & Partners and specifically Ralph Freeman who did the detailed design,' said a Hyder spokesman.The bridge is often referred to as 'The Coathanger' due to its steel arch design, which is composed of two 28 panel arch trusses. Their heights vary from 18 m at the center of the arch to 57 m beside its pylons. It stands 134m above mean sea level and spans 509 m. The steel used for the bridge was 79% imported from Middlesbrough, the rest was Australian. Its anniversary date is March 19th. Sir Douglas Fox & Partners became Freeman Fox in 1938, which merged to form Acer in 1987, which became Hyder in 1996.
