Blue line: Mall must be reorganized
TVA looks at how the Le Boulevard mall at Jean‑Talon and Pie‑IX has to be be partly demolished and the rest reorganized as construction for the blue line begins.

The parking lot at the NW corner will soon be replaced with a giant hole in the ground. The tunnel boring machine will start from this point and travel eastwards. Traditional tunneling will also start from here and travel westwards to St. Michel station. The overall footprint of the workspace at ground level will be much larger than what you can see at the REM Marie-Curie station. This is why part of the mall will be demolished. Since STM is now the owner of the mall, they can make their tenants move out.

James when you say “traditional tunneling” westward that’ll also be the boring machine?

Traditional tunnelling: drill and blast or roadheaders. I suppose the technique used will be decided by the contractor selected by the STM.
Since the distance to travel westwards to the St-Michel tail tracks is only about 500m it doesn’t make sense to use a TBM. If you wanted a TBM for the entire distance of the blue line extension you would have to make a giant hole in a residential neighborhood (intersection of Jean-Talon & 17th av.) and then start going eastwards.
