Roads of National Significance
The protected route for the Warkworth to Te Hana project travels west of Warkworth and east of both Wellsford and Te Hana, connecting back into State Highway 1 near Waimanu Road.
The project is 26km long, and the indicative design includes an 850m long twin bore tunnel in the Dome Valley and three interchanges located at Warkworth, Wellsford and Te Hana.
We expect to begin procurement, enabling works, and construction of Ara Tūhono Warkworth to Te Hana within the next 3 years.
There will be a number of benefits as a result of the project including:
The indicative alignment for Ara Tūhono – Warkworth to Te Hana connects to the Ara Tūhono – Pūhoi to Warkworth section to the northwest of Warkworth and heads north, crossing Woodcocks and Kaipara Flats Roads.
The new highway will be located in a separate valley, to the west of the existing SH1, until it reaches the Hoteo River where it will head eastwards crossing over the existing SH1 and Wayby Valley Road, with an interchange proposed at Wayby Valley Road.
The highway then continues generally parallel to Wayby Valley Road, before turning northwards and crossing Rustybrook Road. As the highway heads north it will cross local roads including Whangaripo Valley, Farmers Lime and Silver Hill roads, bypassing both Wellsford and Te Hana townships.
A further interchange is proposed near Mangawhai Road, with the new highway then connecting back into the existing SH1 to the north of Waimanu Road, just past Te Hana.
The project team is working closely with regional and iwi partners to deliver the Ara Tūhono – Warkworth to Wellsford project.
