Strengthening works to Aro Aro Bridge on State Highway 2 in the Waioeka Gorge are underway this week.

The NZ Transport Agency says some traffic restrictions will apply from Monday, February 10.

Works have commenced on site to prepare for the strengthening works but traffic will only be affected from February10.

A single lane closure with speed restrictions will be in place for six weeks from February 10. This is to allow the works to be completed safely.

NZTA Bay of Plenty system manager Rob Campbell says motorists should plan ahead and allow extra time for their journeys.

'The Transport Agency thanks motorists for their patience.”
