SH1 Mangamuka Gorge Expected To Reopen Tomorrow
State Highway 1 Mangamuka Gorge will remain closed overnight and is expected to reopen tomorrow (Friday 2 May).
Contractors are continuing the clean-up of the slip site and removal of at-risk vegetation.
Concrete barriers will be installed in the road shoulder at the slip site tomorrow morning to stop any remaining material that may fall during future weather events from reaching the road and requiring road or lane closures. Following this, NZTA will be in a position to confirm when the road will reopen.
People should continue to use the detour via State Highway 10 in the meantime.
NZTA understands any closure of the gorge is disruptive, especially for freight, local businesses, and communities. We appreciate everyone’s patience as we work to get the road reopened as soon as we are able to do so safely.
