The bridge was built in the late 1880s as part of the Maroondah Aqueduct system which carried water from the Maroondah Reservoir to Melbourne. The system consisted of 25 miles of open cement and brick lined channels, 12 tunnels and 14 wrought iron siphons (pipes) to carry the water over ravines such as the Plenty River.
The Bridge’s pipes were replaced with a stainless steel pipe in 1977, which was relocated under the Plenty River. The Pipe Bridge structure remains intact, with a portion of original pipe located nearby, beside the walking trail on the eastern side of the river.
Bring your own pen for the log.
