Hey UT,

There has been interest on other Urban Toronto threads to start a thread here on Ottawa's Confederation Line LRT, currently under construction and set to open in 2018.

You can find all the project info at http://www.confederationline.ca/ , as well as weekly updates from the project team.

Thanks for this. Excited to see the progress. Very interesting tunnelling under downtown - perhaps a precursor to what we'll see here for the relief line. Ottawa is either marsh or Canadian Shield so by no means is it an easy task.

Some of the more interesting construction update photos from the past month.


East of Lyon Station, things are starting to look like a real tunnel!

Tremblay Station is taking shape.

Most other photos are of yet more unfinished tunnel, or of generic construction activities that are generally unremarkable.
