VANCOUVER – The second tunnel boring machine has broken through to the future site of the Oak-VGH Station of the Broadway Subway project in Vancouver.
The machine, nicknamed Elsie, broke through the station’s east wall just after 10 a.m. on Saturday, Oct. 28, following the project’s other tunnel-boring machine, Phyllis, which broke through on Oct. 12.
The two machines have each bored two kilometres of parallel tunnels and have installed more than 2,600 concrete tunnel-liner rings since departing from Great Northern Way-Emily Carr Station.
Phyllis will soon go forward to the South Granville area, with Elsie to follow after scheduled maintenance.
The Broadway Subway Project is a 5.7-kilometre extension of the Millennium Line from VCC-Clark Station to West Broadway and Arbutus Street, extending down the Broadway Corridor, one of the most heavily used corridors in Vancouver. The Oak-VGH Station is the fourth of six underground stations along the future Broadway subway corridor.
Construction of the concrete walls, columns and floors is underway in various stages at all six stations. The first section of concrete floor for the concourse level has been installed at the future Mount Pleasant Station. Crews continue to build the concrete deck at the 700-metre-long elevated guideway section that connects the Broadway Subway Project to the existing Millennium Line in preparation for track work, a provincial government release stated.
