About Tharwa Bridge
Tharwa Bridge is a heritage-listed Allan truss road bridge spanning the Murrumbidgee River at Tharwa, about 35 kilometres south of Canberra in the Australian Capital Territory. Completed in 1895, it is the oldest surviving bridge in the ACT and a rare intact example of Percy Allan's timber truss design. Notable for its four timber spans, heritage listing and scenic river setting, it remains in use carrying Naas Road.
Visitors guide
Visitors can expect a historic timber truss bridge still carrying traffic over the Murrumbidgee River in a rural village setting. The structure features four Allan truss spans with timber decking and steel reinforcement from conservation works. Views extend over the river corridor, river flats and surrounding hills. There is roadside parking and interpretive signage explaining the bridge's history and engineering. The area is quiet and suitable for short walks, photography and viewing the river from the bridge approaches.
