Victoria Bridge, Timber trestle bridge in Picton, Australia.

Victoria Bridge is a wrought iron box plate girder bridge across the Nepean River at Penrith, on the Great Western Highway. It was designed by John Whitton, Engineer-in-Chief of the New South Wales Government Railways, and built from 1862 to 1867, with William Piper, Peto Brassey and Betts supplying the superstructure and William Watkins the piers. It originally carried a railway line and a single lane of road.

Designed by John Whitton, Engineer-in-Chief of NSW Railways, and checked in Britain by John Fowler, the bridge was built from 1862 to 1867 by William Piper, Peto Brassey and Betts, with William Watkins as pier contractor. It replaced two timber toll bridges of 1855 and 1857 that floods destroyed, and carried rail and horse-drawn traffic until 1907, when it became a road bridge on the Great Western Highway.

The bridge's name honors Queen Victoria, reflecting the British influence on place names during Australia's colonial era. Walking across it today, you encounter a structure that served to connect isolated communities during a formative period of the region's development.

The bridge carries the Great Western Highway on a single lane in each direction, with no separate footway, so pedestrians share the roadway with traffic. It stands where the highway crosses the Nepean River at Penrith, and the wrought iron box plate girders and stone piers can be seen from the riverbanks at either end. Traffic is heavy: about 25,000 vehicles crossed daily in 2009.

The bridge's ironwork was checked in Britain by John Fowler, John Whitton's brother-in-law and a renowned railway engineer. Whitton was Engineer-in-Chief of New South Wales Government Railways. The structure is listed as RTA Bridge No. 333 and joined the New South Wales State Heritage Register on 27 May 2016.
