The south is the largest future urban growth area in Auckland, with around 5,000 hectares of land identified for urban development across an area that includes Pukekohe, Drury, Paerata and Takanini. Improvements to SH1 from Papakura to Bombay is a priority within the Supporting Growth Programme.
Auckland is growing, fast. Around 1.7 million people currently live in Auckland and over the next 30 years this could grow by another 720,000 people to reach 2.4 million.
The south is the largest future urban growth area in Auckland, with around 5,000 hectares of land identified for urban development. Over the next 30 years, southern growth areas such as Pukekohe, Drury, Paerata, and Takanini, could provide up to 40,000 new homes, as well as new jobs.
The SH1 Papakura to Bombay improvements project is a priority project within the wider Supporting Growth Programme(external link)
This project’s improvements will support the growth of communities by improving access along and across the motorway, enhancing local connectivity and resilience. Staged delivery combined with early route protection, will achieve value for money by enabling responsiveness to changes in demand, technology, and the environment.
The SH1 Papakura to Bombay project will build on the improvements delivered by the Southern Corridor improvements project between Manukau and Papakura.
The first stage, between Papakura and Drury, is expected to be constructed within the next decade.
It will deliver:
The second stage of the project from Drury to Bombay is likely to be built in the longer term, in line with the projections for longer term population growth and release of land in new growth areas.
In mid-2018 the NZ Transport Agency board approved the business case for SH1 Papakura to Bombay. Over the next few years, the project team will develop the design of stage 1 further and lodge statutory approval applications. As part of this next stage, the team will meet with neighbouring property owners to talk about the project’s expected footprint, and discuss the process to be followed over this period.
The project plans to include a new shared walking and cycling path along the western side of the motorway corridor. It will continue on from the shared path being constructed as part of the Southern Corridor Improvements Project. The path will connect with communities on either side of the motorway. As well as connections at interchanges, there will also be connections to local roads along the route. We’re also investigating walking and cycling only cross-motorway connections. These connections would enable the development of planned future walking and cycling networks.
The amount of growth planned for in the south of Auckland means we need to adopt smarter ways of moving people and freight. We also need to take account of what the motorway is like further north and what the existing constraints are.
Intelligent Transport Systems, such as lane control signals and variable speed limits, are being investigated as part of this project to help manage congestion and motorway access. Along with CCTV, these systems help improve incident detection and management capability.
We are also considering the way in which additional lanes could be used to more efficiently move people and goods. This could be done by reserving lanes for specific customers such as trucks carrying freight, or vehicles carrying more than one person. Wider shoulders could also be used by emergency vehicles.
