Broadway Subway check-in: Guideway progress and tunnelling towards completion – Construct Connect

November 27, 2023

With the Broadway Subway Project (BSP) reaching a pivotal phase, marked by the near completion of the concrete deck of the elevated guideway linking VCC-Clark to the future Great Northern Way-Emily Carr Station, it’s an opportune time to examine recent progress of this massive undertaking.

Central to the project’s success are the two tunnel-boring machines, Elsie and Phyllis. Each having bored two kilometres of parallel tunnels and installed over 2,600 concrete tunnel-liner rings, their work marks substantial progress in the underground construction phase.

As the machines excavate, they simultaneously install precast concrete segments, creating a stable tunnel lining and minimizing surface disruption.

This approach is particularly vital in dense urban areas, where maintaining the integrity of existing infrastructure is crucial, explains the project website.
