Grafton Bridge, Multi-level bridge in Grafton, Australia

Grafton Bridge is a multi-level steel structure spanning across the river to connect two sections of town. The truss design uses reinforced supports to carry traffic while allowing water vessels to pass beneath its spans.

A Clarence River crossing at Grafton was first proposed in 1915 as a railway bridge with a footway; in 1922 the design was altered to carry road traffic too. The New South Wales Public Works Department built it from 1927 to 1932 with steelwork from Clyde Engineering, after private tenders came in too costly. Governor-General Sir Isaac Isaacs opened it on 19 July 1932, completing the standard gauge line between Sydney and Brisbane.

The structure holds official heritage status in New South Wales, marking its role in the region's engineering story. It stands as a visible landmark that locals and visitors alike recognize as part of Grafton's built environment.

The bridge accommodates both vehicles and pedestrians, serving as a key crossing point between different areas of town. It is straightforward to walk across and functions smoothly for all forms of traffic.

The bascule span was operational from 1932 until 1969, when it was sealed shut after shipping on the Clarence River declined. A water main now runs through the space reserved for a second rail track, so the span can no longer be raised. The heritage listing also covers three remnant spans of the 1915 timber viaduct south of Grafton railway station, still standing in parkland.
