Why is such a tunnel needed?

I found such a photo on the Internet and became interested in what function such a structure could perform.

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

It actually takes 50 million to make these? Gimme 50 good men who want to be millionaires and we can figure out the capital cost between us.

A lot of the money is probably sunk into ecological surveys, permits, bureaucracy overall
