A number of concrete bridges crossed the Silvan Outflow Aqueduct as it passed through Mt Evelyn.

Those most easily seen today are in the section from Hunter Road to Priestley Crescent, where the open channel is preserved. Bridges remain at both Hunter and Priestley, and there are three more in between. These would have given landowners living above the channel access to Olinda Creek below it.

There were three bridges on the Aqueduct where it flowed through Mt Evelyn township: opposite the end of Station Street (where a right-of-way still leads down to Clematis Road); at Channel Road and at West Hill Drive. Part of the West Hill bridge is still visible, though the channel below it has been filled in.

In addition, there were several siphons, where the open channel fed into a pipe. The siphons had log-catchers to keep debris from clogging the pipes, and retarding basins to slow the flow of water.

The basins were named after local residents. Rice's Basin was located just above Priestley Crescent. From there the water ran in three steel pipelines to Smith's Basin on what is now Hazel Street (then part of McKillop Road). It ran in a concrete 'grade siphon' and tunnel diagonally across Monbulk Road. At Joy Avenue, Fall's Basin began the siphon parallel to the Lilydale-Warburton rail line. Ellis Basin, above Johns Crescent, headed the siphon down to and under Lilydale-Montrose Road (Swansea Road) and Olinda Creek, and up to the Olinda Reservoir.

Rice's and Ellis Basins, or rather their sites, can still be seen. The basins have been filled in to ground level, but the excavations in the hillsides above reveal their locations.
