This week's wind storm has highlighted problems that remain in the Bay Bridge's construction.
"'The combination of the weight of the traffic and the force of the wind exceeded the capacity of this temporary repair.'

He said the bridge should be shut down for a few days until all relevant beams can be inspected for hairline cracks with X-ray equipment."
