Burdekin River Rail Bridge, Railway bridge in Queensland, Australia.

The Burdekin River Rail Bridge is a disused metal truss bridge beside the current crossing at Macrossan, in the Charters Towers Region. It has six riveted 250-foot (76 m) Pratt truss spans, flanked on each side by four 50-foot (15 m) plate girder spans carried on cast iron and concrete piers. The track sat on the lower chord, the floor was fully decked and a substantial handrail ran along it.

The Great Northern Railway reached Macrossan in 1882, crossing the Burdekin on a low road bridge converted for rail, which flooded repeatedly, once under 17 m of water in March 1890. Swanson Brothers won the contract on 26 May 1896 for a projected £52,143, and the new bridge opened on 17 January 1899, designed under Chief Engineer Henry Charles Stanley. It carried trains until the replacement bridge opened upstream on 16 May 1964.

Locals call it the Macrossan Bridge, after the crossing where the Great Northern Railway met the Burdekin. Its purpose was to carry gold from the Charters Towers field to the port of Townsville, and the line also served the pastoral industry. The old bridge stands beside its 1964 replacement, and its eastern timber approach spans, 132 m in all, have been removed.

The bridge is visible from nearby areas on both sides of the river, offering good vantage points to view the structure from the banks. Plan to visit during dry weather to get the clearest views of the crossing and its surroundings.

The bridge deck sits 3 metres above the highest known flood level, a response to the 1890 flood that submerged the earlier road bridge under 55 feet of water. Its six 250-foot steel spans rest on piers and basalt cutwater quoins founded on rock, and the track runs along the lower chord.
