The Terrace Tunnel was officially opened on Sunday evening following a major upgrade. 8 new 90kW jet fans were installed in the roof and 1100 new high pressure sodium lights were fitted. In addition, a deluge system designed to suppress a fire in the tunnel was installed. It is capable of delivering Wellington’s annual rainfall in just over 3 minutes. A public walk through followed the opening which 5000 people turned out for. Not bad for a Sunday night.
