Travel on State Highway 1 (SH1) between South Auckland and the city centre will be safer and more reliable for commuters with a range of improvements between Papakura and Drury South to support significant residential and employment growth in South Auckland.
The project, part of Auckland's Supporting Growth Programme, will provide better travel options, with upgraded rail capacity, new walking and cycling facilities and improved highway access and safety.
With an additional 120,000 people expected to live in the area over the next 30 years, these improvements will provide greater choice for how people in the local area travel to work, access local services or connect with family and friends.
The NZ Upgrade Programme will provide an estimated $423 million to fund improvements on SH1 between Papakura and Drury South to improve travel reliability. This will connect with the improvements we have just completed on the Southern Corridor, extending the highway to six lanes.
This project includes building a third lane – in each direction – along 6kms of the existing highway, upgrading the Drury interchange, and widening three bridges to accommodate the extra traffic lanes. This project also allows for planned improvements to the adjacent rail line – the new stations at Drury and electrification of the rail line from Papakura to Pukekohe.
In conjunction with these corridor improvements, the SH1 corridor upgrade will be extended from Drury to a new Drury South interchange, connecting SH1 with Mill Road. This further corridor upgrade will include a third lane in each direction, along with an extension of the separated shared walking and cycling path to connect through to facilities on Mill Road.
A separated shared walking and cycling path will also be built adjacent to the highway, along the northbound lane, to link in with the city-wide network being developed.
We will also investigate opportunities for a dedicated public transport lane and/or for use by vehicles carrying multiple people.
