Fonterra and the NZ Transport Agency are planning to improve traffic safety on State Highway 1 outside the company's dairy factory at Kauri, between Whangarei and Hikurangi.
The dairy giant is spending about $1 million and the transport agency has earmarked $300,000 to provide better access to the dairy factory and improve safety at the merger of the passing lanes adjacent to the Fonterra site.
Fonterra has already moved a roadside house, power lines, a fence and removed trees to provide room for road widening work expected to start this week and be completed by the end of April.
Under-road detectors have been installed, which activate warning signs on the highway to signal when a tanker is leaving or turning into the site. New intersection lighting has also been completed to make the factory entrance more visible at night.
More cars on the road and a change to the road layout since the factory was built in 1989 have meant the area has become increasingly dangerous.
