Road users can expect 10-minute delays when travelling State Highway 2 between Wairoa and Napier as the demolition of the old Waikare Gorge Bridge starts on Monday, October 30.
The work is expected to take between five and six weeks with crews on site from 7am to 6pm Monday to Sunday.
The temporary Bailey bridge currently controlled by traffic lights will be operational 24/7 while work is carried out in the river and to the side of the road reducing effects on traffic flow.
TREC project director Tony Gallager said the removal of the destroyed bridge is important in the recovery of the road through the gorge that was destroyed during Cyclone Gabrielle.
