    I've seen it and a few others on recent road trips.

    Additionally, Colorado (and other states) are putting these "animal escape ramps" along the sides of highways.

    From what I can gather, a fence runs along the freeway on both sides—presumably to keep the wildlife out. But, I suppose in case an animal makes it into the danger zone, every mile or so there are dirt berms built against the fence that provide a way up and over the fence. Presumably they drop off on the other side so an animal is not as likely to use these in reverse: to get into the danger zone.

    Additionally, there are often small partitions at each berm, jutting out from the fence. I imagine an animal following along the fence—when they arrive at the partition, they either go around it and continue, or do the right thing: climb the berm to get to the other side of the fence.

    As expected from the press release at open about 9 months ago. (they estimated 90% reduction https://news.ycombinator.com/item?id=46321557)

    The $15M price tag still seems like a lot. Happy for the critters and motorists tho

      The ROI is beyond solid. It's actually insane this wasn't done sooner at this location. The normal ROI for a wildlife crossing is 15 years. Here, it's two to three years.

      > Cost savings: Each prevented wildlife–vehicle collision can save thousands of dollars—more than $19,000 per deer crash, $73,000 per elk, and $110,000 per moose—in vehicle, injury, and wildlife costs, making well-placed crossings a strong investment [0]

      This section of highway had one deer-vehicle collision per day.

      365 * $19,000 = $6,935,000 per year.

      edit: this post and resulting thread made me realize that "wildlife crossing" sounds far too tree-hugger for our society. They need to rebrand to "obvious money-saving infrastructure," or better.

      $15M is less than 4 Patriot PAC-3 MSEs. Which do you prefer your taxes to be spent on?
    • kazinatoran hour ago
      $15M is dirt cheap for the USA. That buys you like 100 yards of urban light rail or something. :)
      • coryrcan hour ago
        If I did the math right, Seattle-area Federal Way Link Extension costs $185k per yard, getting 81 yards for $15M.

        God we're terrible at building things.

          Is that the California high speed rail I see trying to hide in the back?

      Cool - want to suggest changes to the legal code to lower the cost?
    • sophacles2 hours ago
      Instead of doing that boring thing the unthinking do - I challenge you to ask why 15M seems like a lot.

      Is it a lot in comparrison to the costs to the taxpayers for all the emergency crews responding to animal caused accidents over the lifetime of the crossing, not to mention dealing with carcasses of animals, etc?

      How much of any single person's tax money went into it? How long until those few cents get paid off in terms of saved time and gas by not dealing with the traffic backup from those accidents? How much do those few cents amortize to your savings in reduced insurance since thats less potential accident you have to bet against... how much savings does that reduction confer on your expected direct costs in cas you had been in a the accident?

      Does 15M still seem like a lot?

      Maybe you think it could be built cheaper - how? Show your work.

      All these things sure are an interesting conversation to have. Much more interesting than "hur dur, 15M is a big number" anyway.

      • Terr_an hour ago
        Just trying some napkin math...

        Some quick searching gives a claimed collision costs to everybody of ~$7k per event.

        Supposing it's $15m and that it'd lasts 30 years, then it just needs to stop ~71 events per year to "pay for itself".

        'Course, that's the cost of collisions rather than any near-misses or other problems.

      This is peak bean soup theory on HN.

      Always has to be at least one commenter, "but what about my highly specific scenario? All the other people benefiting are an aberration to my specific need or wild singular example"

      Fund SNAP, not discount game meat through the deaths of others.

      • probablyStimmed2 hours ago
        Nailed it. Adding the fact that the majority of HN comments are negative or at least at odds with the post, HN is a bean soup fallacy/theory/dilemma generation system.
      • consumer4512 hours ago
        Agree 100%. Also, hitting a deer at highway speeds can lead to the death of the occupants of the vehicle.

        This is not some country road!

        This is an actual win-win scenario, for humans and wildlife.

      • ducktoysleftout2 hours ago
        SNAP is funded. Food pantries are abundant. Nobody is eating roadkill to survive as a matter of necessity. If you’re eating carrion that’s probably a lifestyle choice and indicative of some mental illness.

        A wildlife overpass is certainly not going to be cheap, but I could see the road user safety benefit penciling out over the life of the asset. I wonder why you would send the animals over (and span the whole roadway) rather than under (cut and cover a box culvert). Either way, it would be nice to see this better funded for rural America.

        • gausswhoan hour ago
          The CBS article (https://www.cbsnews.com/colorado/news/largest-wildlife-overp...) mentions there's one large overpass which gets all the attention, but also there's five underpasses. There's a photo of some deer using one towards the bottom.
        • ghostsigns2 hours ago
          The lives of the animals also matter.

          On a related note, they don’t send them under because most wild animals do not like enclosed tunnels and would not use them.

          > SNAP is funded.

          Disregarding the weird roadkill thing: That's a facile measure, 100% of $5 that nobody is eligible to receive is "funded".

          In 2025 Republicans slashed its budget by the biggest cut in history, and today participation is the lowest in 17 years.

          I doubt any of us honestly believe the drop is because everybody's financial situation has gotten way better right now, or because groceries got cheaper.

          Wrong.

          Especially in places that culturally frown upon wasted food / meat.

      > there are many people that have a significant reliance on roadkill to fulfill their dietary needs.

      I doubt that many people are collecting roadkill on a 75mph 6-lane divided freeway though, since I can't really think of any safe way to collect it.

      But even if you could collect it, hitting anything small at that speed will completely pulverize it, and hitting anything larger will seriously hurt the vehicle's occupants, so it's probably best to stick to smaller roads.

    • dendrite92 hours ago
      Last thought before the deer goes through my windshield and kills me is: "At least someone can eat this roadkill."

      Reducing car/animal collisions is a good thing for cars(drivers) and animals.

    • probablyStimmed2 hours ago
      Ignoring my incredulity at this response, the risk to the lives of the drivers seems to me to be of greater importance than the potential that some people might benefit from the carcasses lying on the side of road.

        I have to admit, my life would be a little more boring without some of the hot takes I find here sometimes

        Like, maybe I can just buy you a cheeseburger instead of totalling my car

      > going to bed with a deep hunger in the pit of one's stomach.

      I'm fine with that, as their dinner shouldn't depend on me suffering an horrible car crash and being hurt or killed.

      The people will save a lot of money if they don't need to replace 500 cars each year, therefore more money to feed themselves. They will not be forced to eat dog corpses.

    "This area was getting about one deer hit a day"

    Relative to how many didn't get hit, what's the percentage there?

    • majormajor2 hours ago
      I'm curious about the POV you're coming from. I don't think the number of deer who don't get hit is relevant to the math on injury prevention, traffic prevention, and ongoing operational and property damage costs.
      • kazinatoran hour ago
        Well, yes; for that you need the number of cars that that don't hit a deer. :)
