The State Highway 1 intersection with State Highway 29 has been called one of New Zealand’s most dangerous
A replacement for a “dangerous” intersection connecting the Waikato and Tauranga has the tick.
Plans for a two-lane roundabout at the T-junction of SH1 and SH29 in Piarere, north of Tīrau now have consent from the Environment Court.
The court previously heard how the intersection – a key connector for Auckland, Waikato and the Bay of Plenty – regularly backs up 51m in afternoon peak periods.
Waka Kotahi had brought forward plans for the roundabout due to “ongoing crash risk”, the court heard, and the Cambridge Chamber of Commerce submitted that it was “one of the most dangerous intersections on New Zealand’s roading network”.
The roundabout now has Environment Court approval and a list of conditions to comply with, including noise and dust limits, and communication, environmental and traffic management plans.
Waka Kotahi will have to work around assets on the Hinuera – Karapiro A 110kV power transmission line, and follow bat and lizard management plans, among other conditions.
Construction of the roundabout is expected to take 18 months.
The switch to a roundabout was expected to bring “an 87 percent reduction in reported injury crashes, and a 29 percent reduction in death and serious injury crashes”, the court heard.
The roundabout site is just northwest of the current intersection, on Thistlehurst Dairy Limited farm, the decision said, and parts of SH1 and SH29 would need realignment.
