The tunnel-boring machine named Phyllis saw daylight this past Saturday when it broke through the underground box for Mount Pleasant Station of SkyTrain’s Millennium Line Broadway Extension.

This comes almost exactly two months after her sister, Elsie, arrived at Mount Pleasant in late January.

According to the provincial government, Phyllis has now excavated 725 metres of tunnel and installed 494 concrete liner rings between the tunnel-boring staging area at Great Northern Way-Emily Carr Station and Mount Pleasant Station, which is located at the intersection of Main Street and East Broadway.

Once the machines enter the underground station boxes, they are incrementally moved to the other end of the box on steel rails, and regular maintenance is also conducted during this downtime before the machines restart their boring and tunnel construction process.

Elsie resumed digging on March 4 for her next breakthrough, which will be at Broadway-City Hall, where a major interchange transfer hub between the Canada Line and Millennium Line will be established.
