Southbound on and off ramps at the Te Kauwhata Interchange will be closed next week as State Highway 1 road works at Rangiriri enter their final phase.
Waka Kotahi NZ Transport Agency said work in the northbound lanes would finish this week, and traffic would be moved on to those lanes while the work began on the southbound lanes after Sunday, November 5.
For local traffic, the switch overnight meant the southbound on and off ramps at the Te Kauwhata interchange would be closed, so traffic would need to use the Rangiriri ramps to come and go from the Waikato Expressway.
There were also three separate repair sites outside the current work areas which would be worked on later in November with less traffic management and disruption.
Progress depended on weather and investigation work, Waka Kotahi said.
