Vancouver’s Broadway Subway Project – Second TBM Breaks Through

Broadway Subway Project Breakthrough

The excavation process of future Broadway-City Hall Station, was commenced by the second of two Herrenknecht TBMs digging twin tunnels for Vancouver’s Broadway Subway Project.

Following arrival of TBM Elsie’s in April, the breakthrough by TBM Phyllis on 27 May was done.

The future Great Northern Way-Emily Carr Station was the location of commissioning TBM Phyllis in November 2022, while it excavated 1,350m of tunnel and installed 884 rings.

A planned maintenance is due to be applied to these two 6m diameter machines.

As the deepest station built for the Broadway Subway Project, the Broadway-City Hall Station will be at 20m underground, allowing the new tunnels to travel underneath the existing Canada Line. While its extension will be 210m over two blocks, this station is slated to be the largest and busiest station on the Millennium Line SkyTrain extension.

The responsibility of constructing the Broadway Subway Project was up to Acciona-Ghella JV, whereas it is a 5.7km extension of the Millennium Line from VCC-Clark Station to West Broadway and Arbutus Street, comprising of 5km of tunnels and six underground stations. The determined date for inauguration of this project is 2026.
