Virtual Sidewalk Supers can read about Laird excavation

Sidewalk Superintendents of the virtual kind may find interest in the linked details of how excavation work is being done at the Laird LRT station site at Laird Drive and Eglinton Ave. It’s described as the sequential excavation method (a mining technique) suitable apparently to digging out the space needed for underground platforms and concourse levels. Metrolinx says this means “once the excavation is complete for the station entrances, a total of two at Laird, we will start mining sideways under the roadway to make room for the platforms and concourse. In contrast, the cut and cover method means excavating vertically from the road.” Going deep into the ground at Laird Station.  Ah yes, but will the cars be green or red?
