Snapshot of Carleton Station - December 27, 2020
The southern and northern underpass pits, I believe both are now at their final depths The southern pit has wooden barriers. I'm not too familiar with the construction but I now believe that the tunnel stub will be within the southern underpass. It is off to the side of where I think the underpass will be so I'm not sure what the barriers would be for it otherwise. It is also far closer to the Carleton University tunnel system for future attachment.
