The Lennox Bridge (also known as The Horseshoe Bridge) is a stone arch bridge designed by David Lennox situated in Glenbrook, Australia. It is a single arch of 6m (20-feet) span and 9m (30 feet) above water level, with a road width of 9m (30 feet)[1]
The bridge, opened in 1833, is the oldest surviving stone arch bridge on the Australian mainland.[3][4][5] It crosses Brookside Creek (also known as Lapstone Creek) on the road known as Mitchells Pass. It replaced an earlier crossing of the creek 600 metres further south, which today survives as a walking track. A nearby quarry is thought to have been created for the purpose of providing stone for the bridge.[2]
The bridge served the main route to the Blue Mountains for 93 years until 1926, when the Great Western Highway was re-routed via the Knapsack Viaduct.[6] It was closed in 1967 but later strengthened and repaired with an internal concrete structure and it re-opened in 1982.[2][5]
