Elsie launched from the future Great Northern Way-Emily Carr station in October and has been moving steadily west. She arrived at the Mount Pleasant site in late January.

The second tunnel boring machine, Phyllis, is expected to launch again from Mount Pleasant next week and arrive at Broadway-City Hall later in the spring.

The future station will connect Millennium Line passengers to the Canada Line, and is expected to be the busiest and largest station in the SkyTrain extension. The station is being designed to handle higher volumes, with a second elevator and additional escalators, the Transport Ministry said.

More than 20 meters underground, the station will also be the deepest station ever built for the project. Its tunnels will be under the existing Canada Line tunnels.

The Broadway Subway project will extend the Millennium Line nearly four miles from the VCC-Clark station to Broadway and Arbutus Street. The first section from VCC-Clark to Great Northern Way-Emily Carr Station will be above ground. The next five stops will be underground.

It is scheduled for completion in early 2026, delayed from its original target date of late 2025 due to a concrete strike last year.
