Frightening moment wind blows truck over on Auckland Harbour Bridge caught on camera

The moment a truck was blown onto a tilt as it crossed the Auckland Harbour Bridge has been caught on camera.

Video footage captured at about 11am on Friday shows the truck driving in the centre lane of the bridge before the wind gusts, blowing the truck onto a tilt. The truck is left leaning against the bridge structure. 

"Oh bro, it's going over," one person yells in the video.

After being stuck for a few moments, the truck righted itself. 

Warning: The video contains strong language.

"We need to get off this f***ing bridge, man," said a person. 

The New Zealand Transport Agency (NZTA) earlier on Friday said winds were gusting at more than 60kph before suddenly picking up to 127kph for a few minutes.

NZTA Auckland system manager Andrew Williamson said a southbound truck carrying a shipping container "was blown sideways and hit the bridge superstructure".

"The truck righted itself and carried on. There is damage to the bridge overarch, with a steel upright sheared off".

At the same time, another medium-sized truck travelling in the centre of the bridge northbound "was hit by a strong gust of wind and blown across two lanes".

"It toppled over the moveable lane barrier and is now stuck on the barrier. The driver was not injured," Williamson said at 12:45pm. 

All northbound lanes were closed briefly at 12:50pm while authorities attempted to recover the crashed truck. However, two lanes north and two lanes south are now open and traffic is moving slowly.

The centre lanes are expected to remain closed for some time to come while structural engineers assess the damage. 

St John responded to the truck crashes and said that one person had been injured and was in a moderation condition.

Due to congestion, motorists have been asked to consider using the Western Ring Route around the harbour instead of crossing via the bridge.

The worst of the winds have now past, Metservice says.
