It appears that preliminary NZTA engineering designs indicated 313 tonnes of additional steel were needed for the current clip-on repair. And on that basis work commenced. But now NZTA advise that over 900 tonnes of steel were actually used.
(After repair) I am advised that this 600 tonne increase seriously compromises the carrying capacity of Auckland's Harbour Bridge because the clip-ons are now so heavy they can barely support their own weight – let alone the weight of traffic.This public fiasco should not be obscured by debates about the next harbour crossing.
