Remedial works on State Highway 1 at Rangiriri move into the final phase next week.
Waka Kotahi NZ Transport Agency advises the current work in the northbound lanes will finish this week, and traffic will be moved on to those lanes while the focus switches to work on the southbound lanes after Sunday 5 November.
However progress depends on weather and investigation work.
There are three separate repair sites outside the current work areas which will be worked later in November with less traffic management and disruption.
For local traffic, the switch overnight on 5 November means the southbound on and off ramps at the Te Kauwhata Interchange will be closed – so traffic will need to use the Rangiriri ramps to come and go from the Waikato Expressway.
The surfacing repairs began in September and have been extended to a late-November finish after further works were identified in the investigation stages after traffic was moved.
With the changing layout people are asked to take extra care when travelling through the interchanges by following any temporary speed limits, traffic management and signs.
When the current works are complete a 70km/h speed restriction will remain for a settling period ahead of final surfacing.
Waka Kotahi encourages people to allow extra time if travelling on this section of the expressway, recommending they merge early into a single lane to help lessen congestion.
Waka Kotahi apologises for the disruption this work is causing and thanks people for their patience.
