Drivers on the Te Rapa section of the Waikato Expressway are in for three months of disruptions as workers add a new layer of seal along a 6km stretch.
NZTA Waka Kotahi has advised motorists to plan ahead with work already underway on the section of expressway, from the Te Wetini Dr - Wairere Dr overbridge near Wintec through to the Horotiu Interchange.
Workers began the project last week, which would see the existing road surface overlaid with a new layer of structural asphalt.
NZTA regional manager infrastructure delivery Jo Wilton said once complete, the Te Rapa section of the Expressway would have a smoother and more durable surface.
Night closures and detours were being used to allow crews to work inside the single-lane sections of road.
