File:Sydney Metro Mabel arrives at Sydney Harbour’s edge

Description
Tunnel boring machine (TBM) Mabel reached Blues Point in January 2020. This marked the end of tunnelling in the city’s north.

Since launching in February 2019, Mabel travelled 6.2 kilometres underground from Chatswood via new metro railway stations at Crows Nest and Victoria Cross.

This historic milestone marked the completion of the twin tunnels between Chatswood and the edge of Sydney Harbour, an important step in extending Sydney Metro into the city.
