"This is the best day of my career, without a doubt. In future every person who drives through here will be able to do so safely," she said.
NZTA regional relations manager Steve Mutton said the roundabout and Klinac Lane extension would improve safety, allow better connections within Waipapa, make the area more cycle- and pedestrian-friendly, reduce congestion and slow traffic. Local businesses would suffer some disruption, but ultimately it would improve the local economy, he said.
The sod-turning was entrusted to Mr Jones, Northland MP Matt King and Waipapa Business Association representative Sarah Curtis, who said the project was testament to Cr Court's persistence.
"We're glad it's finally paid off," she said.
Work has started already on shifting utilities such as water and power. Stormwater will be improved and overhead power lines will be placed underground.
The next phase will be to extend Klinac Lane from the commercial centre of Waipapa to connect with Waipapa Loop Rd, which will include building a short bridge.
Once that is complete, around March-April, Klinac Lane will serve as a detour at times while work on the intersection is under way. The roundabout is due to be completed by the end of 2020.
