The Broadway Subway Project has hit another milestone with Phyllis, the second of two massive tunnel-boring machines, breaking through to the future Broadway-City Hall Station in Vancouver.
Phyllis has excavated 1,350 metres of tunnel and installed 884 liner rings since starting at the future Great Northern Way-Emily Carr Station in late November 2022.
Elise, the other tunnel boring machine, reached the station on April 14, 2023. Her next stop will be at the future Oak-VGH Station, passing the halfway point in tunnelling toward the future Arbutus Station terminus.
The new Broadway-City Hall Station is the deepest station along Broadway at more than 20 metres underground, so that the Millennium Line extension can be built underneath the active Canada Line. The station stretches 210 metres over two blocks under Broadway between Alberta and Cambie streets to provide space for a crossover section of track where trains can switch directions when needed.
The station will have additional capacity for the expected volume of transit users, including passenger connections being built underneath Cambie Street, in order for people to easily transfer between the north-south Canada Line and the east-west Millennium Line.
Earlier this month at the Broadway-City Hall Station site, a pedestrian bridge was installed to reconnect the south sidewalk between Alberta and Yukon streets. It is one of several installed in the station blocks along Broadway that, combined with the traffic decks, keep people moving and preserve access to this transportation and retail corridor while work on the underground stations carries on below.
Progress continues to be made at the elevated guideway where crews are installing the deck on top of the completed girders that connect the 21 columns between VCC-Clark Station and the future Great Northern Way-Emily Carr Station. Construction is also ongoing at all six station locations with activities ranging from excavation, concrete pours, waterproofing, rebar installation and station wall construction.
