Nope, just completely ignorant of the process...
So to be clear, the lanes on Eglinton will be closed down in order to build the launch shaft, sometime in the coming weeks? It takes over a year to built a launch shaft?
From what I recall, the Black Creek launch shaft started construction in late 2011, and tunnelling didn't start until summer 2013. However I think they started tunnelling later than was originally scheduled (I think it was supposed to start late 2012).
Anyways, yes it can take a year or more to construct the launch shaft lol.
At least we can check the tunnelling progress now that the first two TBMs are digging. Now that the Spadina extension is done tunnelling there doesn't seem to be as much news to follow on that line.
