Second TBM breaks through on Vancouver subway
29 May 2023The second of two Herrenknecht TBMs excavating twin tunnels for Vancouver’s Broadway Subway Project has broken through at the future Broadway-City Hall Station.
The breakthrough by TBM Phyllis on Saturday follows TBM Elsie’s arrival in April.
TBM Phyllis was launched at the future Great Northern Way-Emily Carr Station in November and excavated 1,350m of tunnel and installed 884 rings.
The two 6m diameter machines will now undergo planned maintenance.
At 20m underground, Broadway-City Hall Station will be the deepest station constructed for the Broadway Subway Project, allowing the new tunnels to travel underneath the existing Canada Line. Stretching 210m over two blocks, it will also be the largest and busiest station on the Millennium Line SkyTrain extension.
The Broadway Subway Project, being constructed by the Acciona-Ghella JV, is a 5.7km extension of the Millennium Line from VCC-Clark Station to West Broadway and Arbutus Street. It includes 5km of tunnels and six underground stations. It is scheduled to open in 2026.
