So I thought I'd google it and found something I've never heard of -- animal bridges for animal crossings. Evidently, we're planning one here over a major highway. The article about it is here, and this is what it might look like:

We have some wetlands right down the street and sometimes on the way to the store traffic will be stopped for a family of geese crossing. We also have a couple of ducks who hang out under the drive-thru window at the local Arbys -- I'm sure that can't be good for them. And we have our very own personal blue heron who routinely stops in our backyard to menace the goldfish. Maybe we can eventually make language a complete impediment to understanding. -Hobbes
Regarding animal bridges here: yes, they are common along newer highways and railways. Mostly in mountainous areas, but for example the Budapest-Vienna highway in the border region (which is flat or has low hills, wind power plant country) must have about a dozen, mostly for rabbits (but I have cycled over one). Here is a link to a page with two webcams looking at the construction of a railway gallery [= open-to-one-side tunnel] along a line doubling in Austria; on the second you'll notice the outer "bridgehead" of what will be a rather wide animal bridge over the old line.
On your continent, they must exist at least in Canada too: I think I saw a photograph of one in, what must have it been, a National Geographic article on Banff national park? *Lunatic*, n. One whose delusions are out of fashion.
This is a lovely area and there's quite a lot of nature here. In fact, I'm so enthusiastic about it that when my friends visit I tend to bore them with listing all the fine qualities. The Chamber of Commerce should be paying me.
The proposed animal bridge in my comment is also in the mountains -- over Interstate 90 through the Cascade range. Maybe we can eventually make language a complete impediment to understanding. -Hobbes
you can see the cow bridge on this image better, together with the Schwebebahn.
At least I think it was this bridge... I know that one of the bridges had to be build, for cow-traffic because the motorway cut in half the field of one farmer. and he agreed to the road being run across his land, if they build the bridge.
They had to lower the bed of the river underneath so they could build the motorway underneath the Schwebebahn. and had to raise the Schwebebahn by 2.20m plus they had to stretch the existing rail bridge from 20 to 130 meters. all just for the Autobahn...
