The project scope included a 21.5-kilometre upgrade to Mill Road Corridor, providing an additional route between Manukau and Drury.
This would have seen the current two-lane route upgraded into a four-lane corridor, including separated walking and cycling facilities, and provide more reliable public transport services.
The project delivery stages comprised:
- Takaanini Section - Alfriston Road to Old Wairoa Road
- Papakura Section - Old Wairoa Road to Hunua Road, and
- Drury Section - Hunua Road to SH1 in Drury South
|Apr 2018||The estimated NZ$507 million Mill Road Corridor (phase 1) was included in the updated 2018 ATAP as an investment priority for the 2018-2028 decade. The project was also included in the Draft Regional Land Transport Plan (2018-2028).|
|Jan 2020||The NZ Upgrade Program provided an estimated NZ$1.35 billion to complete all stages of Mill Road.|
|Mar 2021||The 2021-31 investment package of the Auckland Transport Alignment Project included Mill Road Corridor as a fully funded commitment.|
|Jun 2021||Following a re-evaluation of the New Zealand Upgrade Program (NZUP), the existing proposal for Mill Road Corridor was deferred, with no indication of future timelines. Instead, a smaller scope of works was proposed to upgrade existing two-lane Mill Road from Flat Bush to Alfriston. Targeted safety upgrades between Alfriston and Papakura is also part of the new scope. Value of this work was not confirmed.|
