The Balclutha Road Bridge, which spans the Clutha River in Balclutha, South Otago, New Zealand, is one of the best-known road bridges in New Zealand's South Island.

Built between 1933 and 1935, this bowstring bridge was designed by W. L. Newnham to be earthquake and flood resistant, thereby safeguarding it against the two most common natural disasters to occur in southern New Zealand.

The bridge is built from reinforced concrete, with six parabolic curved spans, each of 36.6 metres in length, and a total bridge length of 244.1 metres.

The first, constructed in 1868, was destroyed in massive floods ten years later when a bridge situated upstream at Beaumont was swept downriver and collided with it.

A second bridge was constructed in 1881, but was unsuitable for the needs of motorised transport and was eventually replaced by the current structure.
