SH1 Brynderwyn Hills – works completed ahead of schedule and road fully open

SH1 over Brynderwyn Hills is now fully open and ready for summer travel, ahead of schedule.

All resurfacing work is complete, passing lanes are reinstated, and the 80km/h speed limit has been restored – making journeys to and from Northland smoother.


Travel safely – the new asphalt surface can be slippery when wet as it wears in, so take extra care.

Despite some heavy rain early in the closure, our teams worked day and night with a finely tuned programme to keep everything on track so the road could reopen as quickly as possible.


This marks the completion of the recovery project, and the second planned super weekend closure from 20–23 November is no longer needed.



Road resurfacing work for the completion of the SH1 Brynderwyn Hills recovery project and maintenance included:

  • 160 people on the ground
  • 4,500 hours worked over four days
  • 3,800 tonnes of asphalt applied
  • 115 round trips in total to get the asphalt to site. That is nearly 28,000km travelled just to get the asphalt to site!


To make the most of the full closure, 9 different crews also completed maintenance tasks that normally require manual traffic control. This means extra travel delays have also been avoided this summer. This work involved vegetation control, removing litter, drainage maintenance, guardrail repairs, wire rope repairs, retaining wall inspections and sign replacements and cleaning. More than 100 maintenance dispatches were completed.



A huge thank you to everyone involved and to all road users for your patience while we completed these critical works.
