Kawarau Falls Bridge is a modern two-lane bridge on SH6, over the Kawarau River at Frankton, New Zealand. The project contains 780 tonne of Weathering Steel.

The bridge will reduce traffic congestion, increase safety and provide more secure southern highway access into the Wakatipu Basin.

The new bridge will provide:

  • two full traffic lanes
  • sealed shoulders suitable for cycling
  • footpath on one side of the bridge
  • an enhanced southern highway entrance to Queenstown

The new two-lane bridge will be built just downstream from the existing bridge with a modified northern approach from Frankton. The southern approach will tie in with the present highway that runs along the river bank. It will be approximately 250 metres long and 14 metres wide constructed on a curve with a 163 metre radius and designed to withstand a once in every 2,500 year earthquake.

The new bridge design comprises four steel beams spanning between single column piers located 45 metres apart, with a slim superstructure that compliments the form of the existing dam structure. Guardrails that meet safety requirements will maximise the views of the river for bridge users.
