Second TBM on Broadway Subway project breaks through at future Mount Pleasant Station
The Broadway Subway project in Vancouver, B.C., marked another construction milestone last week when Phyllis, the second of two tunnel-boring machines (TBMs) digging the project’s twin tunnels, broke through to the future Mount Pleasant Station.
TBM Phyllis began work last fall and excavated 725 meters (0.45 miles) of tunnel and installed 494 concrete liner rings between Great Northern Way and Mount Pleasant along the new section of tunnel.
Elsie, the first TBM , launched Oct. 7, 2022, and broke through at Mount Pleasant Station in January 2023. Both TBMs are approximately 150 meters (492.1 feet) long and were customer built for the Broadway Subway project.
Elsewhere on the project, crews are installing girders to connect columns along the elevated guideway and excavation and construction of the station foundations are ongoing at the Broadway-City Hall, Oak-VGH, South Granville and Arbutus sites.
