How do humans protect wild animals from entering public infrastructure like highways or train railways?

Answer 1

By herding animals over, under and around those infrastructures via fences, burms (e.g., hills), land bridges, and tunnels. This topic has a lot to do with migration patterns of wildlife and strategically placing underground tunnels or land bridges to match migration or seasonal feeding patterns of animals like elk where they cross. Fences and land fences I called burms above are placed to push and ‘herd’ the animals to those safe crossings.

This is at least a start from someone who has been around wildlife all his life. Hopefully someone more knowledgeable will come along.
