I found such a photo on the Internet and became interested in what function such a structure could perform.
My guess is that it will be a “nature highway” so migratory species can cross over the road

These are great for wildlife as they provide a safe crossing over high-speed highways. They are usually design to be in already existing migration paths where moving a proposed highway may not work and not disrupting migration paths is of importance.
So they're literally building the mountain next year. Neat.
They dug it out before. Later they rebuild it. But if they wait for a year, nature suffers much.
Looks like a nice choke point for a predator to hang about.
Possibly but I’d think it’s still safer than vehicles and less disruptive to overall migration for a given species.
I wonder if there’s been any studies showing how effective, if at all, these are.
There have been study's, these crossing are usually design to feel like open fields in a sense, so most animals will cross quick and on high alert to get through the "opening" in the field.
Are there any predators smart enough to strategize like this? I know that some use water holes as hunting grounds, but that's probably more instinctive than actual strategy.

it is the predators that build such passages. Have you ever seen any construction company building them? Even in the first photo that is under construction, there is not any human worker in sight

Sure looks like an animal crossing.
Why do they put deer crossing signs on the highway? Why can’t they put them on smaller roads instead‽
Also, deer can't read street signs, so they don't know where to cross.

This is the one! They're ridiculously effective, so much so that my home provinces is sinking like 250 million into building 5 more of them over the next 5 years

Will there be compacted earth on top of the tunnel so animals can walk?
Yep, they call them land bridges. More of a hill than a mountain, but the meme is right!
This is cool. This is the first time I have heard about such projects.

That's an unfinished nature bridge.
Quite a common feature in Europe. Gives the animals safe passage over busy roads.
not just that but it saves human lives as well by reducing animal collisions.

More or less safe. Predators often camp these choke points for obvious reasons.
I read pedesterians often camp these choke points. I was picturing hobo joe sitting there to catch a passing rabbit or deer for a good meal.

They disrupt the nature a little less. Animals aren’t hit crossing the street because they can go over and other small benefits like that. They also look nice and tunnels are fun when your car sounds nice
Yep, I love a good nature bridge!
It's not finished. It will look like this when they complete it. It's a nature bridge.

The caption is a joke, but it's basically correct.
We had a few of these built in my country to allow wildlife to cross safely.
We’ve had a few of these built on my planet too actually

This kind of looks like the new one they're building in Banff National park. I drove through over the summer when they started it. They have a bunch of them set up throughout the park.

Coquihalla highway has something like this to keep avalanches and rocks off the road.
It's the only tunnel I've driven that has windows.

// TODO: Support mountain package when it releases
Could be for a skii-slope as well. There are similar structures in Are, Sweden for example.

I Are they are used to ski over the road, it enables the slope to go all the way to the city cente.
