Balclutha Road Bridge, Tied-arch road bridge in Clutha District, New Zealand.

Balclutha Road Bridge is a bowstring road bridge over the Clutha River, built from reinforced concrete with six parabolic spans each 36.6 metres long and a total length of 244.1 metres. Its 6.7-metre carriageway is flanked by 1.4-metre footpaths, giving a total width of 11.8 metres. It carries State Highway 1 between Dunedin and Invercargill.

The bridge was constructed between 1933 and 1935 to replace earlier structures damaged by severe flooding and changing traffic demands. This project represented an important engineering advancement for managing major river crossings in the region at that time.

Locals call it "The Clutha Bridge", though many bridges cross the country's second-longest river. It carries State Highway 1 between Dunedin and Invercargill, and the Balclutha Rail Bridge stands several hundred metres downstream.

Visitors can cross the bridge on foot or by vehicle as it forms part of the main highway route through the area. Both footpaths and the roadway are accessible year-round and accommodate regular traffic flow.

The structure incorporates advanced engineering features designed specifically to withstand earthquakes and flooding, which were notable innovations for New Zealand in the 1930s. These protective design choices made it more durable than other bridges built during the same period.
