Lennox Bridge in Glenbrook is the oldest bridge on the Australian mainland (predated by the Richmond Bridge in Tasmania, completed 1825). This single-arch sandstone bridge was designed by David Lennox, a bridge builder and stonemason who emigrated to Australia in 1832 after the death of his wife. Before his arrival in August 1832, the new colony of New South Wales had no skilled stonemasons, and Lennox was a Master Stonemason with 20 years experience. After a chance meeting with the Surveyor-General, Major Thomas Mitchell, David Lennox was appointed Sub-Inspector of Bridges and later Superintendent of Bridges for the colony.
Lennox Bridge was completed in July 1833 by David Lennox and a party of 20 convicts. It is constructed with large sandstone blocks from a local quarry with a single arch of 6m (20-feet) span and 9m (30 feet) above water level, with a road width of 9m (30 feet). Due to its design, it is also known as Horseshoe Bridge.
The significance of Lennox Bridge is that it allowed the Great Western Highway through Mitchell's Pass over Lapstone Creek and opened up the development of the Blue Mountains and western NSW. The bridge served the main route to the Blue Mountains for 93 years until 1926 when the Great Western Highway was re-routed along the old railway line over Knapsack Viaduct. In 1967 Lennox Bridge was closed for restoration work and strengthened with concrete, reopening to traffic in 1982.
David Lennox also designed Lennox Bridge over Parramatta River in nearby Parramatta, as many other bridges also including 53 bridges in the Port Phillip (Melbourne) area.
