Work to repair a bridge on State Highway 2 is expected to start next month.
The rail overbridge at Ōringi, approximately eight kilometres from Dannevirke, was damaged in late March when a truck collided with it.
Waka Kotahi NZ Transport Agency manager for Manawatū-Whanganui, Rob Service, said up to 15 metres of concrete barrier on the side of the northbound lane was severely damaged in the crash.
Service said the bridge was structurally sound and had been assessed as safe to travel across but has been down to a single lane and under temporary traffic management since the incident.
Waka Kotahi’s main priority was getting that section of the highway back open to two lanes as soon as possible.
