Burwood rail underbridge, Railway bridge in Burwood, Australia

The Burwood rail underbridge is a single-span, 21.9-metre metal half-through plate web girder bridge over Burwood Road. It carries the double Main Suburban line on a three-girder arrangement: the two outer girders are 1892 wrought iron, while the 1926 inner girder is steel. Cross girders support a concrete deck with ballasted tracks.

The bridge was built in stages: the outer wrought-iron girders date from 1892, when John Ahern held the government contract, and the inner steel girder was added in 1926. The three-girder arrangement carries the middle two tracks of the six-track Main Suburban line over Burwood Road. It was listed on the New South Wales State Heritage Register on 2 April 1999.

The bridge carries the middle two tracks of the six-track Main Suburban line, so express and suburban trains pass on either side of its girders. Its 1892 outer wrought-iron girders and 1926 inner steel girder make it a visible record of how the corridor was widened. The maker's plate on the north side of the Up outer girder reads "John Ahern 1892 Govt Contract".

The underbridge is visible from Burwood Road and easily accessible for viewing the structure from nearby locations. Visit during daytime to see trains passing and observe the engineering details more clearly.

The structure displays an original Maker's Plate from 1892 that documents its construction details and craftsmanship. This marking preserves the identity of the builders and makes it a documented example of industrial heritage.
