Barnes Railway Bridge crosses the River Thames in London in a northwest to southeast direction at Barnes. It carries the South West Trains Hounslow Loop Line, and lies between Barnes Bridge and Chiswick stations. It can also be crossed on foot, and is only one of three bridges in London to combine pedestrian and rail use; the others being the Fulham Railway Bridge and Hungerford Bridge. .
Built in 1849 to a design by Joseph Locke – and looking very similar to the current Richmond Railway Bridge which he also designed – it was rebuilt by the London & South Western Railway in 1895. The original Locke span still stands unused on the upstream side.
