“It sounds like the traffic light pole took a bit of a beating,” he said.
Whanganui District Council has placed a temporary roundabout at the intersection.
Repairs are expected to take about three weeks, as special parts need to be ordered.
The council said a new pole and lantern assembly would be installed and the electrical damage to the controller cabinet needed to be fixed.
The council asked drivers to take care and follow directions when driving through the intersection or use an alternative route.
