Queanbeyan railway bridges over Queanbeyan and Molonglo Rivers

The Queanbeyan railway bridges are two separate structures crossing the Queanbeyan and Molonglo Rivers using steel Warren deck trusses supported by brick and stone piers. The two spans were designed to handle regular rail traffic while maintaining their original positions above the waterways.

The original bridges were built between 1885 and 1887 using arched hardwood timber and brick piers for the river crossings. A major reconstruction in 1926 replaced the timber with steel Warren trusses, giving the structures their current form.

The bridges, listed in the State Heritage Register since 1999, represent the evolution of New South Wales railway infrastructure and engineering practices from the 19th century.

The bridges remain in active use by trains on the Bombala railway line and are best viewed from the riverbanks or nearby access points. Visitors can observe them from a distance without interfering with rail operations.

The Warren deck truss design appears at only four other railway sites in New South Wales, making these structures regionally significant. This rare engineering approach represents an important phase in how Australian railways were built during the late 1800s.
