That's a wildlife bridge in progress. It allows wild animals to cross the highway without getting run over.
235When we design things like this in reclamation, there is often the concern that the designed feature can act like a trap or increase predation. There was an article a while back that showed that these are actually safe, and blend into the surrounding landscape in terms of risk to the animals.
Oh look, someone actually backing their viewpoint up on the internet:
26I sent it better to funnel wildlife into traps for predators than to have the wildlife killed by vehicles on a road, attracting those predators onto the road seeking out their carcasses only to be hit by vehicles themselves?
Many owls and raptors get killed because they are trying to feed on a carcass in the road and get hit themselves.

They do something similar with railway underpasses, place the tunnel and build the embankment later.
16Also seen one like this that's avalanche defences.
13Got to protect those Mako reactors!

Seems like they already done the wildlife bridge, what yet to finish is the animal crossing that goes on top of the wildlife bridge.
5Ah thank you for the context!
5How do they know to cross the road through the bridge instead of road. It's not like they understand that the bridge is for them to cross safely.
Also we have to construct many bridges throughout the road across forest area. Isn't it cheaper to build flyover for vehicles instead.
3I'm assuming you're asking in good faith.
With these corridors, they fence the road so that the animals can only pass over the bridge. And youre right, sometimes they do raise the road and let animals pass under. It depends on the topography.
