The John Whitton Bridge is a railway bridge that carries the Main Northern railway line across the Parramatta River, located between the Sydney suburbs of Rhodes and Meadowbank.

The original double track Meadowbank Bridge opened on 17 September 1886 as part of the construction of the Main Northern railway line.

It was a lattice truss bridge designed by John Whitton, the Chief Engineer of the New South Wales Government Railways.

[2] As part of plans to quadruple the Main North line, construction commenced on a new bridge to the west of the existing structure.

Work resumed in the 1970s, with a two-track box girder bridge opening in May 1980.
