About the notice of requirement
The requirement applies to an area of land of approximately 76.9 hectares over a corridor length of approximately 5km located between the intersection of Mill Road and Alfriston Road and a new intersection with Papakura-Clevedon Road.
The project is for the construction, operation and maintenance of a state highway and associated activities between the intersection of Mill Road and Alfriston Road and a new intersection with Papakura-Clevedon Road. The proposed alignment deviates up to 1.6km to the east of the existing Mill Road-Cosgrave Road between Takaanini and Ardmore.
In summary, the proposed work includes:
- Four 3.5m traffic lanes – i.e. two lanes per direction.
- Wire rope median and roadside barriers, with 1.5m sealed central width and 1.0m shoulder width.
- Dual-lane at-grade roundabouts at three key intersections:
Realigned connection at Popes Road / Phillip Road;
- Airfield Road; and
- Southern tie-in with Papakura-Clevedon Road.
- A new bridge structure (approximately 200m in length) crossing the Papakura Stream and Phillip Road.
- Closure of Hamlin Road on either side of the alignment.
- Raising the road levels from the existing ground level for flood resilience.
- Cut batter slopes and fill embankments, including preload (earthworks).
- Stormwater management devices including conveyance, treatment, and attenuation swales, diversion drains, a treatment wetland, and cross culverts.
- Associated construction activities including site access construction, establishment of site compound and construction laydown areas, vegetation clearance, building demolition, installation of environmental controls, traffic management, relocation and protection of utilities and services.
