SH1 Brynderwyns scenic detour announcement

Three scenic routes are available to access Northland during the closure later this month. The alternative routes are similar to those used during previous closures but will have increased signage and wayfinding to help people navigate these detours.

Alternative scenic routes:

  • Cove Road detour – suggested for light vehicles.
  • Paparoa Oakleigh Road detour – trucks and trucks with trailers up to 50 tonnes can use this route
  • SH12 / SH14 detour – suggested for heavy vehicles, high productivity motor vehicles (HPMV) must use this route

Some detour routes are local roads and may be used by pedestrians, people on bikes, cars and trucks so we ask everyone to drive to the conditions and share the road with care.

For more details about alternative scenie route into Northland, read the frequently ask questions page.
