The massive piece of equipment that will excavate the tunnels for Montreal’s blue line metro extension was unveiled on Monday.
The 9.7-metre wide tunnel boring machine will dig through rock to create the tunnel from the future Vertières station to the Anjou station — a stretch of 4.6 kilometres.
It’s being described as the largest such drill in Quebec and an “engineering feat rarely seen” in the province.
Tunnelling will begin in April and won’t stop until the work is complete.
The tunnel boring machine arrived in Quebec in October and needed to be assembled.
More coming.
