The new section of road is a short bypass that rejoins SH1 before the intersection and was expected to remain in place until September 2024. The intersection would continue to operate as normal.
Motorists were advised to take extra caution when driving through the site.
An average of 20,000 vehicles travel through the SH1/SH29 intersection daily. It is a vital link between Auckland, Waikato and the Bay of Plenty, but has long been known as a notorious area for serious and fatal crashes.
