The NZ Transport Agency (NZTA) is planning to reduce the speed limit on State Highway One around the Puhoi intersection early next year due to the high crash rate in the area.
NZTA is beginning consultation to extend the 80kph limit from the Johnstones Hill Tunnels to beyond the intersection with Puhoi Road.
NZTA Northland safety and network performance manager Tim Crow says it initially planned to install a responsive sign, which would only reduce the speed limit when a car on Puhoi Road approached the intersection. However, a traffic survey found that the high level of traffic would mean the sign would be activated almost permanently.
A crash reduction study found there were six crashes at the intersection between 2011 and 2015, resulting in two serious and six minor injuries.
“In all of the injury outcomes, the conflict occurred between traffic turning right out of Puhoi Road and northbound traffic on State Highway 1,” Mr Crow says.
