📋 Tender Overview
Te Ahu a Turanga: Manawatu Tararua Highway - the gateway between Palmerston North, the Tararua District and beyond has this morning opened to traffic.
The first vehicles have now started travelling over Te Ahu a Turanga, the new 11.5 kilometre highway connecting Ashhurst to Woodville.
The highway has officially become State Highway 3, replacing the old Manawatu Gorge Road, which closed in 2017 following slips.
From the west, the road crosses the Manawatu River over the 300 metre long Parahaki Bridge, and then over the Eco-Viaduct, which takes motorists across an ecologically sensitive wetland complete with swamp maire and raupo.
The road then climbs through the Ruahine Range, with cuts to the hills of 55 metres and embankments 28 metres high - many of which are benched - sloping backwards to minimise the risk of erosion.
The road weaves between the wind turbines, flanked by the shared user path on one side and thousands of new native plants along the highway. All up, more than 1.8 million plants have been added to the landscape - along the road and also away from it.
A special occasion
Project Manager Grant Kauri says seeing the first vehicles travel the road this morning was a special moment.
The closure of the Manawatu Gorge road had such a significant impact on people in Manawatu and Tararua. We know the surrounding communities have struggled with the closure so being able to build them a significantly more resilient, safer and efficient road has been a huge privilege.
The roads importance to the wider central and lower North Island, including the East Coast, cant be overstated. Te Ahu a Turanga will encourage more travel, while supporting economic growth in the regional economies, says Mr Kauri.
Community support and connection
Communities either side of the gorge are equally invested and excited about the new highway.
Joy Kopa, from the Positively Woodville community group, says residents and businesses in the town have been holding their breath for the opening.
It is strange to think we now have a young generation who have never travelled through the gorge and have no memory of the road that served Woodville for so long. This new highway will be the new gateway to Tararua and Woodville is proud to be the town that welcomes travellers to our district.
Central Economic Development Agency is based in Palmerston North and its CEO Jerry Shearman says the new road will unlock numerous long-term benefits for the region and the country.
With Manawatu being home to one of the three key nodes of distribution and logistics in New Zealand, were beyond excited to have this significant piece of infrastructure completed. The new highway will bring transformative benefits to the Manawatu region and beyond, particularly in strengthening New Zealands national distribution and logistics network.
Opening up this highway supports the growth trajectory of Te Utanganui - the Central New Zealand Distribution Hub and will ultimately make the movement of goods between ports, processing plants, and distribution centres more efficient, attracting new businesses to the area by improving access to central North Island markets and beyond.
In short, Te Ahu a Turanga is a catalyst for economic development, logistical efficiency, and regional resilience and is a crucial development in Stage One of the Manawatu Regional Freight Ring Road project. For Manawatu, it reinforces its role at the heart of New Zealands transport and freight network.
More than a road
Mr Kauri said the project is so much more than a road. The alliance working on the project has placed focus on genuine iwi partnership, health and wellbeing and environmental sustainability.
We worked as partners with five iwi who were represented at all levels of the project, including governance, management and operations. Their crucial role on the project can be seen in many areas but especially in the wetlands and stream diversions and in the array of stunning mahi toi artwork on the lookouts, structures and roundabouts.
The project planted 46 hectares of native forest and created 28 kilometres of stream rehabilitation. It has protected 48 hectares of existing forest and provided pest control of 300 hectares of already protected forest reserve, says Mr Kauri.
More than 2500 people were inducted to work on the project, while an even wider group of suppliers provided materials and equipment.
A key principle of the project is to create enduring community outcomes, which means there is a focus on helping people living in the communities around the project. Some of these aims included, a focus on local and iwi employment, procurement, cultural wellbeing, education and training, and support for schools, charities and community organisations.
Over the past few years, weve had so much support from communities on both sides of the gorge, theyve been with us since day one and were truly grateful to everyone for being so patient with us.
We are honoured to share such a beautiful piece of road and landscape with those communities.
Useful facts
The speed limit will be 100km/h.
