Melton Viaduct, Railway viaduct in Melton, Victoria, Australia

Melton Viaduct is a 375-metre girder and trestle railway viaduct built in 1885 by Victorian Railways. It carries the Serviceton line over the Werribee River valley, now dammed to form Melton Reservoir, south-west of Melton in Victoria.

Victorian Railways built the viaduct in 1885 to open a direct rail route between Melbourne and Ballarat. Its girder and trestle design carried the Serviceton line across the Werribee River valley. The structure was added to the Victorian Heritage Register in 2013.

The viaduct stands as a marker of how railway expansion shaped regional identity and settlement patterns across Victoria during the late 1800s. Walking near it or crossing it by train offers a sense of the confidence that locals had in industrial progress and connection to distant cities.

The viaduct remains in active use with regular trains passing through, so access to walk on it is not possible. Best views come from the shores of Melton Reservoir or from train windows if you travel on services using this route.

The viaduct was added to the Victorian Heritage Register in 2013, recognising it as one of the state's notable 1880s railway structures. It carries the Serviceton line across the Werribee River valley, which was later dammed to form Melton Reservoir, so the crossing now looks out over water rather than the river alone.
