Why is such a tunnel needed?

My guess is that it will be a “nature highway” so migratory species can cross over the road

That's an unfinished nature bridge.

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

It's not finished. It will look like this when they complete it. It's a nature bridge.

We had a few of these built in my country to allow wildlife to cross safely.

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.

Could be for a skii-slope as well. There are similar structures in Are, Sweden for example.

They're probably going to build an overpass on top of it later

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