Now that the tunnel boring machines have completed their journeys, crews are excavating connections between the two tunnels, called cross passages.

This one is between GNW-Emily Carr Station and Mount Pleasant Station, and crews have reached halfway to the other side.

Did you know that each #TunnelBoringMachine has more than 30 components to extract during the TBM disassembly process?

Here, a crane lifts a TBM part out of the excavated Arbutus Station site. The TBM parts will be taken away by truck for refurbishment or recycling.

Have you seen the new mural at the Broadway-City Hall Station?

It features artwork submitted by the community answering the question “Where will the Broadway Subway Project take you?”

The artwork was created by children aged 12 and under during a submission period last year.

Each #TunnelBoringMachine is now being dismantled at Cypress St. Here, a crane lifts a piece of TBM Phyllis out of the excavated Arbutus Station site.

Want to see more? Come have a look at this process through 2 viewing windows on the north side of W. Broadway at Cypress St.

Crews are removing the TBM conveyor system, allowing station construction to proceed unobstructed by tunnelling work.

In this shot of GNW-Emily Carr from mid-April, TBM Phyllis’ conveyor system has already been dismantled, with TBM Elsie still en route to Cypress St.

At South Granville Station, stairs are being constructed in the station entrance. Two escalators will be installed later, one on either side of the stairs.

Glass windows have already been installed at ground level - can you see how the light pours into the station entrance?

Can you spot the crew member in this photo?

In this shot of the future Mount Pleasant station, the concourse-level walls are being constructed for the station entrance building. The concourse level is located between ground level and the platform level.

The installation of SkyTrain tracks is beginning at the elevated guideway!

In this shot, the crew use a mobile crane to unload a shipment of rails for the SkyTrain tracks. The first sections of track were lifted on top of the elevated guideway last week.

#TunnelBoringMachine Elsie has arrived at Arbutus Station!

Elsie’s breakthrough today looked very similar to TBM Phyllis’ arrival in late March, pictured here.

In this shot, you can see Phyllis’ cutterhead poking through and rubble collected inside the pressure chamber.

At the future Arbutus Station, a worker inspects the blue and silver supports.

On top, the crew install a work platform to build the concourse level floor. Once the work platform is complete, the crew begin installing rebar before concrete is poured to complete the floor.

This worker is preparing a column for a concrete pour. What you see now is the steel rebar inside the column that helps strengthen it – this will all be hidden once complete.

There are 11 columns just like this one on the platform level of the future South Granville Station.

#TunnelBoringMachine Phyllis arrived at Cypress Street in late March, and crews are now removing the TBM support equipment.

Here is what Phyllis' conveyor belt looks like all spooled up at Great Northern Way-Emily Carr!

Here we can see the future Arbutus Station, where #TunnelBoringMachine Elsie will be finishing her journey soon.

Softer soil conditions near Cypress St. make TBM breakthroughs at this location a little different.

Using a specialized pressure chamber, pressure is equalized with the TBMs’ cutterheads as they break through.

Here are some pieces of the chamber prior to their installation.

Have you seen our latest mural at the future Arbutus Station site?

Come down and take a peek through the viewing windows to catch a glimpse of the #TunnelBoringMachine disassembly taking place at this location.

Recently we shared a flyover video featuring the #BroadwaySubwayProject alignment.

At South Granville Station, #TunnelBoringMachine Phyllis was below the traffic deck, covered with an orange tarp to protect her from the cold.

On March 20, TBM Phyllis broke through at Cypress St.

Due to softer ground conditions near Arbutus Station, the breakthroughs at this location look a little different. Both TBMs break through into a specialised pressure chamber, shown here.

Before entering Great Northern Way-Emily Carr Station, the SkyTrain will transition from the above-ground elevated guideway to the below-ground tunnels.

This section of tunnel is called the “transition box,” as the tracks will transition from above to below ground.

#TunnelBoringMachine disassembly in 6 steps!

Once their jobs are done, both TBMs will be dismantled.

TBM pieces will be lifted out of Arbutus Station using a crane as the machines are taken apart.

In this aerial shot of the elevated guideway, you can see crews constructing small walls, called parapets.

The parapets will run alongside the future SkyTrain tracks!
