All northbound lanes on Auckland’s Harbour Bridge are due to temporarily close so emergency services can remove a truck that rolled in a gust of wind.
Both directions of traffic in the middle of the bridge were affected by the crash.
NZTA said all northbound lanes will close at about 1pm for about half an hour.
Police were called to the crash shortly after 11am.
A police spokesperson said no one is injured and wind is a likely cause of the crash.
Emergency services are working to clear the tipped truck but said it will take some time and motorists should expect delays.
NZTA is warning drivers to avoid the route or delay their journey.
