The Burwood rail underbridge is a heritage-listed railway underbridge located on the Main Southern and Main Western railway lines in the Sydney suburb of Burwood, in the Municipality of Burwood local government area of New South Wales, Australia. The triple-girder underbridge spans Burwood Road. The railway bridge was built from 1892 to 1926 by John Ahern. The property is owned by RailCorp, an agency of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 2 April 1999.



The Burwood rail underbridge is a single-span 21.9-metre (72 ft) metal, half-through plate web girder. It carries the double Main Suburban line (middle two of the six tracks) on a three-girder arrangement - outer girder, down suburban, inner girder, up suburban, outer girder. The term "metal" has been used to draw attention to the fact that the outer girders were part of an 1892 wrought iron bridge whereas the 1926 inner girder is steel. The cross girders carry a concrete deck supporting ballasted tracks. On the north side of the Up outer girder is the makers plate - John Ahern 1892 Govt Contract.


As at 27 March 2006, the physical condition is good.
