The current single lane single bridge built in 1887, is one of a handful of wrought iron bridges left on our highway network. It provides an important link over the Clutha River – Mata-Au on SH8 connecting Dunedin, Central Otago and Queenstown.
A new two-lane bridge is needed as the existing single lane bridge is no longer suited to today’s higher traffic volumes and the heavier trucks now using this route. Traffic signals were introduced several years ago a measure to reduce stress on the wrought iron truss structure, by lowering vehicle speeds over the bridge.
A new two-lane bridge will be designed to handle current and expected traffic growth, including heavier trucks; and meet current earthquake standards. The historic bridge will remain after the new one opens to provide a link to the popular Clutha Gold walking and cycling trail.
A modern new bridge on SH8 over the Clutha River – Mata-Au at Beaumont, will support a transport system for Otago that’s safe, resilient, meets current and future needs, and connects people, products and places.
We plan to have traffic using the new bridge by the last quarter of 2023. Weather and other delays could push this date out. Other on-site work will continue for a few months after the opening including applying a second coat seal to the new bridge traffic lanes.
