Work linking the Huntly and Ngaruawahia sections of the Waikato Expressway will mean a major road layout change at the Gordonton Road interchange at Taupiri from February 12.
The south-bound access lane which takes SH1 traffic on to the Ngaruawahia section will close to enable a full interchange to be constructed as part of the works on the Huntly section.
With the lane removed, traffic will need to use the roundabout above the expressway and take the on-ramp.
The change will be signposted, and will add only a minute or two to journeys.
NZ Transport Agency Delivery Portfolio manager Peter Simcock says works are progressing well on the 15.2km Huntly section.
