Silverwater Bridge is a concrete box girder bridge[2] that spans the Parramatta River west of the central business district in Sydney, New South Wales, Australia.

The bridge carries Silverwater Road (A6) over the river to link Silverwater in the south to Rydalmere and Ermington in the north.

[2][3] It was the first of the two major bridges needed to construct the Hornsby-Heathcote county road (the other being the Alfords Point Bridge), and was the second project undertaken in the construction of this county road (the first being Olympic Drive Lidcombe, between Boorea and Church Streets, in 1959).

The origin of the suburb's name, and subsequently the bridge's name, is unknown.

It may have been a reference to the nearby Parramatta River, which could have provided silver reflections of light off the water.
