This site is frustrating on mobile. Every time I touch the screen to scroll the page, a menu that I don't want slides in to cover the article.

Perhaps not a better website for mobile, but I'm pretty sure the pictured crossings are from Banff national park in Alberta and probably more going into BC. You can see pictures and find more information here:

We have these in Montana, at least on the Flathead Indian Reservation where I lived until recently. It's a great idea and really helps preventable deaths to elk herds.

I'm curious how they are engineering these overpasses to not be slowly torn apart by tree roots, if they even consider that at all.

That's going to happen no matter what. All you can really do is design them to be big and sturdy enough to last roughly as long as the road system. It doesn't make sense to try and severely outlive the roads that they cross.
