The project has replaced and widened the Otaika Bridge to four lanes. The new traffic lights make it safer for traffic turning right into Tarewa Rd or turning left on to and off SH1.
For people walking and cycling, there are new signalised pedestrian crossings at the intersection and a new shared path under the Otaika Bridge. These provide safer, much-needed connections between the city centre, Whangārei Hospital and NorthTec, Thackwray said.
"The traffic lights, the new lane layout and the shared underpass make the intersection safer and more efficient for all road users, whether they are moving about Whangārei or just passing through."
One change is that motorists won't be able to turn right from Tarewa Rd on to SH1.
"This will improve the safety and efficiency of the intersection. A bylaw giving effect to a permanent ban is now in place."
Meanwhile, Northland artist Benjamin Pittman is putting the finishing touches to a striking mural on the shared path under the Otaika Bridge. The mural was designed and painted with help from children at Horahora Primary School.
"Waka Kotahi thanks local road users for their patience and understanding while the SH1/ Tarewa Rd improvements project was completed. The changes now in place will make the intersection safer and more efficient for all road users, including pedestrians and cyclists," Thackwray said.
Work on the project started in September 2018.
