John Monash: Engineering enterprise prior to WW1.

Sewage aqueduct over Johnstone's Creek, Annandale, near Sydney.
Built using the Monier system, 1896. Engineering design by W. J. Baltzer.

Photo. The low-rise Monier arches are carried on thick-set piers. The box-like aqueduct is supported on cross-walls which rise from the arches. The shallow valley is now parkland and the structure is white.

Restoration work was carried out in 1997. This included removal of loose surface concrete and replacement with pneumatically sprayed mortar. (Civil Engineers Australia, Nov. 1997, 34-5.)

A similar structure crosses nearby White's Creek, carrying the same aqueduct. The Johnstone's Ck structure has nine major spans, the White's Ck structure, which is closer to the ground, has eight.
