We have begun building wildlife overpasses over our freeways to allow our mountain lions a chance to improve their biological diversity and to reduce animal strikes.
We do that but, er, for mice. https://www.theguardian.com/environment/2021/nov/30/dormouse-bridge-across-railway-line-could-save-endangered-species
Well, you don't have large wildlife anymore. We need to protect what we have left. CA is celebrating the return of wolves, the offspring of OR-7, the roaming Romeo.
Oh, as you definitely should, I was just joking / contrasting. I do remember a story about a bigger wildlife corridor-bridge (a mile of so wide and planted with woodland) over a motorway, but can’t remember if it was actual or just planned. Very cool idea, though.
I want to see the traffic camera.
