    Why have there been no similar tests on the Mount Victoria Tunnel? Surely as it is such an old structure we should be told about its safety rating.

    Hi Traveller. Mt Victoria tunnel is controlled by NZTA not by WCC. During the closures a year or so back NZTA was doing a lot of work in removing the existing ceiling structure which was in very poor repair regardless of earthquakes. Thankfully that work is now complete which is a significant safety benefit.

    In terms of tunnels per se, as I understand it generally the barrels of the tunnels are pretty strong by virtue of their shape – the weak point is generally the tunnel entrances.

    Regards

    Andy
