In my neighborhood (NY not VA) we had some people make a crossing for these guys this spring

There's precedence in the natural world. A single log can get a lot of use by all types of critters: https://www.youtube.com/watch?v=qsDU_tTgsFw

Do you think that didn’t happen, that you’re significantly smarter about wildlife bridges than the folks who planned this one (who were, apparently, too dumb to ask a question you thought of sixty seconds after reading about the amount of concrete used), or just deeply into throwing shade, deserved or not, at CA at every half-imagined opportunity?

Because I agree about the cost of these things. They should be designed to be inexpensive so we can put them everywhere (eg: i90 through cascades… there is only 1 of these and it’s on the east side of the pass).

It annoys me greatly how seemingly over engineered and expense these are. We put a huge fence that divides the entire mountain range. These bridges should be all over.

That being said I’m pretty sure a lot of research goes into designing a wildlife bridge that animals want to cross. I think there was a practical engineering YouTube video that covered it. Turns out each species has their own preferences and peculiarities when it comes to this sort of thing. So to counter my own argument… it does no good to build a ton of these if no animals will actually feel comfortable using them.

Maybe they should fund some kind of wildlife outreach program and give brochures and flyers to the local wildlife explaining how to use their new overpass…
