Redoubt Road – Mill Road Corridor upgrade

The Redoubt Road – Mill Road upgrade in south Auckland has reached a major milestone, with Auckland Transport accepting a recommendation by planning commissioners to confirm the land requirements for the project.

The upgrade is needed to improve safety and support new housing areas, which will double traffic volumes during the next 10 to 15 years.

Independent commissioners recommended in February that the designation for the land be confirmed, along with a number of conditions to manage the effects of the project.

They concluded that that upgrading the Redoubt-Mill Road corridor is necessary to relieve existing and forecast congestion, accommodate planned growth, provide for alternative modes of transport, improve traffic safety and improve the transport network’s efficiency.

The commissioners found that the effects of the project can be appropriately avoided, remedied or mitigated.

Measures to manage the effects include building 17m and 23m high viaducts above native bush at Puhinui Creek gully and South Mill Road gully, as well as about 22,000 square metres of native planting.

Auckland Transport has accepted the commissioners’ recommendation to designate and the conditions for the project in full.

Auckland Transport Roading Group Manager Andrew Scoggins says submitters have 15 working days to appeal the decision to the Environment Court following being informed by Auckland Council of the decision.
