NZ Transport Agency Waka Kotahi says it is making good progress on the new roundabout at the intersection of State Highway 1 and SH29 at Piarere.
In an update on its website, it confirms most of the foundation works have been completed.
From April 15, traffic south of the roundabout moved on to a newly constructed section of road beside SH1, with roadworkers now focusing their attention on the southern side - the approach to Tīrau.
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.
