A nine-car crash in heavy fog on Auckland's Greenhithe Bridge is causing some delay for northbound motorists.
The multiple nose-to-tail collision happened shortly before 8am today.
A police spokesman said no one was injured in the accident.
However, traffic was backed up to Squadron Drive on the Upper Harbour Highway as the site was cleared.
He said police were in attendance.
Motorists are being urged to exercise caution and be prepared for some delays.
The spokesman said there was also still a bit of fog around impairing visibility.
