Cycling in Waterloo Region

Good point and I somehow didn't think of that. I am not too sure how deep the average sewer lines or any other utility runs on that part of Victoria. In fact the only other pedestrian tunnel crossing I can think of is this one here on Westmount just north of Highland, and I guess it goes just deep enough to not impact the sewer lines (unless there are none there, and storm water drains right into Henry Strum Creek).

If we're including culverts, then there is also one that runs under Lexington where it crosses Laurel Creek.

Culverts are a particuarly easy example, since the bridge already exists....

The Westmount culvert also provides a good example of why they are problematic...between the grade, surface, and lighting, it is downright dangerous before you even take into account that many people including myself on foot, would not feel comfortable using it.  It's worth noting that Westmount plans include a crossing island--which on a busy four lane highway has it's own extremely serious problems, but the very fact it is planned shows how inadequate the tunnel is considered.
