However, it would be ridiculously expensive. Through Uptown, it would have to go under the creek, which means either very tricky tunnelling through muck or going very deep, either of which is expensive. Given the traffic levels and the availability of space on the surface, this simply doesn’t make sense, and as pointed out by others, would have led to non-approval of the project.
On top of the tunneling costs, underground stations (and their associated access, using escalators and elevators) would have added huge costs to the project.
What we have is very much appropriate for Waterloo Region. We also have the option of giving trains traffic light priority should that make sense in the future.
