Connections between Auckland and Northland are set to be made safer and more efficient, and travel times more reliable, with the Ara Tūhono – Pūhoi to Warkworth motorway project.
When it opens in mid-May 2022, the Ara Tūhono – Pūhoi to Warkworth motorway will extend the four-lane Northern Motorway (SH1) 18.5km from the Johnstones Hill tunnels to just north of Warkworth.
The motorway will vastly improve the safety, connectivity and resilience of the network between Northland and Auckland, helping to boost the economic potential of the Northland region.
Under a Public Private Partnership (PPP) contract with Waka Kotahi NZ Transport Agency, the Northern Express Group (NX2) consortium will finance, design, construct, manage and maintain the motorway for up to 25 years following construction.
Beca and Tonkin + Taylor, in a design joint venture, are providing tender design, detailed design and construction phase services for the construction joint venture (CJV) of Fletcher/ACCIONA.
As part of this design joint venture, we are primarily responsible for; the project’s design team leadership and design management, construction phase services of the structures, geotechnical engineering for structures, roading and landscape design, planning, air quality, contaminated land management and sustainability assurance under the Greenroads™ framework.
In conjunction with the CJV, throughout our decision-making and design processes, we have worked collaboratively with the project’s iwi partners Hōkai Nuku, stakeholders and local communities, and maintained an over-arching focus on delivering a safe, high-quality asset and whole-of-life approach.
