The upgraded intersection on State Highway 1 at Tarewa Rd in Whangārei will be fully open to traffic on Monday, the last of six Waka Kotahi NZ Transport Agency projects to improve SH1 through the city.
The traffic lights will be switched on and vehicles will be able to turn right off the highway into Tarewa Rd, Waka Kotahi senior manager project delivery Andrew Thackwray said.
"Turning on the traffic lights effectively signals that the project is completed," he said.
"Waka Kotahi advises all road users to take care and go slowly in the first weeks until they are used to the changes and the new turning opportunities."
He said the SH1/Tarewa Rd upgrade will improve traffic flows, make the intersection safer and reduce queues during peak hours after more than two years of work.
