And now LA’s finally getting one.

This is such a simple, effective solution. We need hundreds of these.

Yes. Have insurance companies fund them.

They’ve been around in Europe for a long ass time. Nature bridges or something, I forgot what they call them. They are pretty cool.

Yeah. It’s fucking absurd that, with the almost 50,000 miles of interstate in the US, there aren’t already hundreds or thousands of these.

The only reason they pushed the one in LA county was because the cougar population is dwindling, largely due to accidents with vehicles while trying to cross the freeway.

Nice to see some good news for a change

Part of the reduction would be in part to the tall fence they put up to keep animals off the interstate also.

It makes sense to do both. Even with the overpass you would have animals that were just following their normal routes and ignoring the new path. By adding a fence to go with the new route it forces animals to change their behavior.

The point is if they would have just done the fence collisions would have be down also. Your answer is just explaining the obvious

Your answer is ignoring the obvious. The actual point is that only doing one or the other would never have led to a 91% reduction. They got these results because they did both. Because it just makes sense to do both.

Fence would lead to a bigger reduction if you could only do one.

In that one particular spot. All you’re doing is moving the issue to wherever the fence ends.

Maybe, but here’s proof that both together are effective. Do you have any evidence to back your claim that the fence alone would be effective? The project cost $15 million for miles of fencing and an overpass. There was an average of 1 car collision with wildlife on this stretch of road every day. Taken in that context, the human lives saved and property damage avoided itself easily pays for the $15 million.

The reason we would need a fence is because the animals are wanting to cross for mating, water, or other reasons. Simply putting up a fence with no way to cross just means the accidents happen somewhere else.

Your wanting the cheap solution with no long term thought. That's Penny Wise, Pound Foolish.

There are already plenty of bridges and under passes that can be used. The fence is 90 percent of the solution and usually there is need for a fence anyway.

A fence with no overpass either gets torned down by animals, or creates its own mess of indirect problems.

The article mentioned elk, bears, deer, and frogs, but what about the chickens ?!

[OP] AlexandrTheTolerable | 9 hours ago

Why would a chicken cross the road?

To KFC

(This is not just to OP, but anyone who comes upon this comment. Welcome to the random yo momma joke,scrubs.)
