James Street Railway Bridge, Lithgow
This relatively small and un-noticed bridge came into service on the same day as the famous Great Zig Zag a few miles closer to Sydney, opened in 1869. Although the Zig Zag has long since been superseded, the James Street bridge remains in service on what is now the East to West ‘Indian Pacific’ route, and seems likely to continue to do so indefinitely into the future.
Although originally bult to carry only single track it was, within a dozen years of its opening, skillfully widened to carry two tracks, such that only careful inspection reveals the modification.
The bridge was designed by John Whitton, father of the NSW railways and built by Patrick Higgins – the same contractor for the Great Zig Zag.
At first placed to carry the railway over a watercourse, it was later adapted to cross a local road so as to remove an adjacent level-crossing from the main line.
