State Highway 2 between Napier and Wairoa will reopen three months after the devastation caused by Cyclone Gabrielle.
More than 100 sections of the road were damaged by landslides, slips, debris and washouts caused by a torrent of water on February 14.
Waka Kotahi, which last month delayed the opening of the Waikare Gorge Bailey bridge until the end of May, said work to restore access along the cyclone-damaged stretch of highway has progressed faster than anticipated thanks to favourable weather.
The highway would now be fully opened on May 14, it said on Friday.
While construction of the Bailey bridge has been continuing, contractors have also been working on a number of other damaged sites, including at the hard hit Devil’s Elbow, and other works to make the road safe.
