Deep Creek Railway Bridge, Railway bridge in North Burnett Region, Australia.

Deep Creek Railway Bridge, also called Chowey Bridge, is a concrete viaduct on the Mungar-Monto line at Didcot. Its central 80-foot concrete arch is flanked by two 15-foot arches, with four 15-foot spandrel arches above the main span; the track runs on sleepers and ballast in a trough. The date 1905 is cast into the sides.

Construction of the bridge began in 1905 under Chief Engineer William Pagan and it opened for rail traffic the same year. It represented an early adoption of concrete arch technology for railway crossings in this part of Australia.

The Queensland Heritage Register listed this railway bridge in 1992 for its demonstration of early twentieth-century engineering practices in the region.

The bridge stands in Didcot, in the North Burnett Region, on the Mungar-Monto line. It is a railway structure, so it is seen from outside rather than walked across; the 1905 date cast into the concrete sides can be read from the ground below. The surrounding land is farming country reached by rural roads.

The bridge's 80-foot (24 m) concrete arch was the third longest span of its type in Queensland and the third concrete arch bridge built in Australia. Its design came from the office of Chief Engineer William Pagan, who in his 1905 annual report called it "a concrete bridge of somewhat novel design".
