State Highway 4 (SH4) between Manunui and National Park will be closed from 8am on Monday 14 April for emergency repairs, due to a tomo or cavity under the road at Mansons Siding, Raurimu.
The highway has been under stop/go here since Wednesday 9 April, but a full closure is needed to undertake repairs, which will involve excavating beyond the centreline.
The work is expected to be complete and the road reopened ahead of the Easter break, but an exact timeframe cannot be determined until more investigations reveal the depth and nature of the cavity.
The detour is significant. It will be via State Highway 41 (SH41) and State Highway 47 (SH47) for all vehicles. This is around 67 kilometres, which adds approximately 52 minutes.
