The Lansdowne Bridge is a heritage-listed road bridge that carries the northbound carriageway of the Hume Highway (route A22 at this point) across Prospect Creek between Lansvale and Lansdowne. Situated in southwestern Sydney it is located on the boundary of the Fairfield and Canterbury-Bankstown local government areas. The bridge was named in honour of Henry Petty-Fitzmaurice, 3rd Marquess of Lansdowne (1780-1863), an Irish Whig politician of the British Parliament (at that time all of Ireland was under British rule and was represented in the British parliament) and associate of the NSW Governor of the day, Sir Richard Bourke.
