Auckland’s City Rail Link (CRL) is celebrating a mighty milestone with its powerful Tunnel Boring Machine (TBM), Dame Whina Cooper, breaking through into the Karanga a Hape Station (Karangahape) construction site at the end of its 860-metre-long journey from Mt Eden.
CRL workers 32 metres below ground at Karangahape welcomed Dame Whina Cooper as the TBM breached a 100-millimetre-thick protective wall of concrete into the station cavern.
