Mungindi Bridge, Concrete bridge in Queensland, Australia

The Mungindi Bridge is a two-lane concrete road bridge carrying the Carnarvon Highway across the Barwon River on the Queensland/New South Wales border at Mungindi. It has a pedestrian footpath on one side and is built higher than its predecessor to improve flood immunity. It replaced a 1914 Dare-type timber truss bridge designed by Harvey Dare.

The first bridge here was a Dare-type timber truss designed by Harvey Dare, one of forty such bridges built in New South Wales. Lawson and Wladro built it in 1914: a single 27.7-metre timber truss span with two timber approach spans at each end, 61.6 metres overall. It was later replaced by the present two-lane concrete bridge, built higher to improve flood immunity and funded jointly by New South Wales and Queensland under the Southern Queensland Accelerated Road Rehabilitation Project.

The bridge serves as a visible boundary between Queensland and New South Wales, and visitors often photograph this spot to mark crossing between the two states. It is a physical landmark that many people recognize when passing through this border region.

The current bridge carries two traffic lanes plus a footpath on one side, so pedestrians cross on that single walkway beside the Carnarvon Highway. It was built higher than the old timber bridge to keep the highway open during Barwon River floods, so check flood warnings before travelling. The old 1914 truss bridge stood at the same crossing.
