State Highway 5 will reopen to all traffic from Napier to Taupō during the day from 7am on Monday.
The March 20 reopening will be one month and one week to the day since it was closed as Cyclone Gabrielle began to ramp up in Hawke’s Bay on February 13.
The road, which travels through devastated Esk Valley, has taken countless man hours to repair and check, and no longer looks “like it did before”, Waka Kotahi said in a statement.
“There are 32 damaged sites along the route, ranging from minor dropouts to significant underslips and washouts.
“There’ll be speed restrictions in place to keep you safe, and there are active work sites. Because of that, the journey between Napier and Taupō will take longer than it used to.
