Summer maintenance season is underwayThe roadworks season is underway in the top of the South Island, and you can expect to see contractors hard at work at multiple locations over the coming months. In Marlborough, approximately 45 lane kilometres of road renewal work will be completed between now and the end of March 2026, including:
The flood damage from June and July is being factored into this season’s work. There’s a lot of activity across the region, but we have planned as best we can to minimise disruption to your journeys. On State Highway 63 there are extensive works planned all the way from Waihopai Valley to the Howard Valley including road rebuilds, resealing, and flood recovery works. State Highway 1 and 6 are also in line for a lot of work. There will be night closures on Weld Pass in November, and three months of road rebuilding work is planned in the New Year on State Highway 1 at Spring Creek from January. Read our media release for more information about the work we have planned in Marlborough. |

Roadworks terminology explainedLane kilometre refers to the amount of highway lane being worked on, not the full width of the road. For example, renewing both lanes of a highway over a one-kilometre distance is equivalent to two lane kilometres of renewal. Road rebuilding (also called pavement rehabilitation) is a full reconstruction of the road. Both the surface and the layers underneath are removed and replaced - sometimes using recycled materials from the original road. After a road is rebuilt with a chipseal surface, crews return about 12 months later to apply a second coat. This helps strengthen the surface and improves waterproofing, making the road last longer. Resurfacing means removing the top layer of the road and replacing it with a new, pre-mixed layer of stone, bitumen, and other materials. This creates a smoother, more durable surface. Resealing involves spraying a layer of hot bitumen or emulsion onto the road, before spreading stone chips over it. These chips take time to settle into the surface, and any loose ones are swept away a few days later. Resilience work proactively improves the transport network by making sections of the state highway network less susceptible to the impacts of severe weather events. |
