It isn't, which is why I prefixed the comment with a note that there likely wasn't enough money in the budget for that, and it would likely be small projects. I'll go change the punctuation and change small to smaller for those who didn't follow.a) That would not be a 'realitvely small project'.
I'd put a portal south of the ravine somewhere, parallel and in the middle of Bathurst. It should only have minor impacts to some properties along Bathurst.Where, exactly, is this tunnel going to surface and how would it connect to Bathurst? You'd be blowing away many rather expensive houses (whose owners and neighbours probably wouldn't be keen on the idea), to say nothing of completely trashing a very attractive ravine.
