came here to say that it went down by over 80% per year, reducing call outs to police, ambulances, fire service, but also increased local business as less shut downs on the highway leading to less traffic congestion leading to less loss in revenue to the businesses in local townships
Sometimes, animals can adapt too much. They built new road next to small lake. This caused an issue for frogs that were trying to get to it. So they made underground passage for animals. Two years later and storks found out that why bother searching for frogs when they have to use this passage. So in the season, you can always see one or two storks standing next to entrance enjoying all you can eat frog buffet
sounds like an issue solved in principle by more bridges. Or maybe it's possible to design the bridge entry and exit in a way that possibly allows frogs to hide out for a bit
In Perth, Australia, there is a nature reserve along the river called the "Canning Reserve". the interesting thing is south of this reserve, the suburbs have been designed with "nature corridors". These are essentially drainage ditches, but are planned to link up the various parks of the area. The idea with these corridors is that animals can move from the reserve to the parks via these corridors. Considering that the reserve is a wetland, and the parks all have small lakes in them (often with reeded areas along the banks), this is designed to supplement the local ecosystem and allow the natural environment to mesh with the suburban environment. Long neck turtles, birds, insects, and amphibians all use this network of corridors to keep each parkland freshly supplied by animals.
Sounds lovely; we have some similar designs in Colorado, though ecology I don't think was the reasoning since it isn't consistent, but our water laws make it possible to sue your neighbor if their rain drains onto your land so we have many creeks and ditches connecting parks that can allow mountain wildlife to go deep into the city
I think one of the biggest difference is that animals can't read signs, while humans don't read signs. Either way, you have to engineer a bridge to be so obvious and intuitive that it won't be disused.
I must correct something. With the dimmensions you provided it definetly is not the biggest in the world. The wildlife crossing near me in Poland (Coordinates via Google Maps: 51.56354422392632, 16.862301457556867) is 310,55 m (1018,85ft) wide and 100,96 m (331,23 ft) long. And I'm pretty sure it is not the biggest either.
Thanks for this correction! You're completely right that the script should have said "largest of its kind." It's unfortunate that both the project's website and several reputable news organizations called it the largest in the world without that important caveat. I've added a note to the description with this correction.
You guys remember the girl that called the radio station asking if they could move the deer crossing sign to a less traveled area? There were too many accidents with deer after they put the deer crossing sign there so the animals knew where to cross.
0:23 Guaranteed that within 24 hours of the crossing being finished there will be an accident with some wildlife and some yahoo will call this project a complete waste of taxpayer dollars.
I'm local to the featured crossing in this video, and have supported it for years. People have been saying that from day one. We have a significant population of people who are against everything, simply because they were told to be.
I LOVE the idea of these animal crossing bridges and think we need to invest much more into them. Imagine how much money and lives we will save with these improvements to our environments.
The first wildlife crossing bridge I ever saw is over I-75 in Florida. It's part of the Cross-Florida Greenway. In addition to facilitating animal movement, it also carries the Florida Trail.
For anyone interested in learning more, the book Crossings by Ben Goldfarb is an amazing look into road ecology and covers a bunch of the topics in this video including the mountain lion P22!
Wow, I had no idea that roads could be so... complicated for wildlife! From 'repelled' animals to 'speeders', it's clear that each species has its own unique challenges when trying to cross a road. And let's not forget about the $8 BILLION in damages and human fatalities caused by wildlife-vehicle collisions each year! The Wallis Annenberg Wildlife Crossing is an amazing example of how investing in infrastructure can make a huge difference for both humans and animals. Thanks, Grady, for sharing your expertise on this fascinating topic!
If English is your first language and you didn’t emigrate from the developed world that is almost certainly not true. You can modify your land such than animals have a hard time but the cops aren’t gonna come out and arrest the frogs & squirrels for trespassing it doesn’t work that way. And animal control will only come for actual nuisances or danger. Also property tax & eminent domain, you don’t own that like you think you do.
You didn't mention Alligator Alley in Florida. When I was in grade school (1974-1976), Weekly Reader discussed the Florida panther and how her numbers were dwindling; she was then endangered. It was a suggestion of school children that started this. The US DOT was skeptical but Florida DOT moved forward with crossings in the Everglades. The number of collisions dropped. Today, such accidents are rare. God must be pleased. Happy holidays to the Hillhouse family from the Frame family.
We call these an "ecoduct". I think it's a fitting name for it. I think it all starts by reversing road entitlement: they are not in our way. We are in their way. This goes for animals on the motorways and other big roads, as well as it does for people in the cities. But since most motorists are also pedestrians and cyclists at some point, the point that cars are more in the way of people than the reverse, is less difficult to grasp. So building infrastructure for animals to cross roads has some overlap with building city infrastructure that's good for people, instead of cars. I'm from The Netherlands btw.
I78 in New Jersey was actually one of the first roads in North America to use wildlife bridges, they were incorporated in the designed phase for the route in the 1980s. If you've ever driven the road you'll know just how striking and awesome these structures can be.
Watching the news it always seems like only terrible things are happening in the world, but the fact we're willing to invest time and real money in projects like this gives me some hope for humanity.
I live in a relatively small town, so seeing a deer isn't too uncommon. Especially in the early morning. Just last week I saw 3 in the corner of an intersection at 4am going to the airport. So it's a good idea to have a deer whistle attached to your vehicle.
Sometime roads are useful for eliminating pest species, brush tail possum and hedgehogs in NZ. In Western Australia, road kill can include kangaroos, camels, goats, deer etc, each decomposing heap will have a scavenger bird standing on top and other birds busy eating the maggots. The cane toad pest ends up as a small leather wallet after baking dry in the sun, these stick to the road for weeks. Most WA vehicles have "roo bars", heavy steel pipe framework in front to prevent the impacted animal coming thru the windscreen.
I've got a fifth category of animals for you. I recently visited Nara, in Japan, where the deer seem to be fairly competent users of the-what we call in England “zebra crossings” (painted crosswalks?). Not perfect in their interpretation of traffic law, but better than the average tourist, to all appearances. Oh, and our local crows have worked out the traffic lights. They can fly anyway, of course, but they use them as a tool, coming in on the red to drop things they want crushed in front of the stopped cars.
0:41 Is that I-90 just east of Snoqualmie Pass in Washington? I always wondered what on earth they were building there. Made no sense as avalanche protection since it slopes upward on both sides, and it’s clearly not for vehicles. Very cool!
where I live in big sky montana, a few dozen elk, and a dozen big horn sheep are hot by trucks and cars each fall, attempting to cross two lane US 191.
@misteral9045 most ecologists stop at the effect on the environment. This many species now endangered, this area of land destroyed. But don't view things like the average cost of road kill on vehicles and so forth. Or are you saying most ecologists already do the humanist thing?
Out here in Phoenix and even in the rural areas when driving to Vegas along the 93, and even once you make it over the Nevada border and you're on the i-11, there is a bunch of wildlife crossings or tunnels underneath roadways and above roadways. They all get used all the time. Some of them have a fencing system so it's almost like a small maze they have to go through to slow down and walk across
I work for the Swedish police to track traffic wounded animals, so this video was right up my alley 👍 Here in Sweden, if you hit any animal like a row deer or bigger, you have to call the police. Even if you don’t think the animal is wounded. The police then sends out one of us trackers, and we do a search for the animal with our dogs to either make sure that the animal is not wounded, or to put it to sleep.
Depending on the State, there are similar laws in the US. As each State is essentially its own country though, there are pretty wide variations on what is considered correct / legal protocol. I know Florida, New York, and California have specific laws regarding animal vehicle collisions. Not too sure about other ones.
@ I know. But I have never seen dogs being used to track wounded or shot animals anywhere in the states. Even when hunting the tracking is made by “hand”. And that’s an almost impossible mission. The dog can track an animal for several kilometers, even without any blood in the tracks. A human can’t do that. And when it comes to traffic accidents, there is almost never blood in the tracks.
They built a crossing a few miles from the area I'm in, the deer learned to cross over it, but the predators also figured out that they could just wait for a free meal..
That was an interesting post. The deer population is way up here in NH as there are few predators so road kill is a problem. Several years ago I had an argument with a deer on the way to work. Not extensive damage to my car and the deer kept going but still cost a few thousand dollars to repair.
This was great timing because today i happened to go somewhere where I needed to pass under the Wallis Annenberg wildlife bridge being constructed. I've watched it go from nothing to what's done now and I can't wait to see how it looks completed.
Appreciate the effort making this video, but beyond the information and commentary, very, very little 'engineering' discussed. I was expecting information how these pathways are built vs the 'engineering' of how to lead wildlife to the pathways.
We have these crossings for decades here in Holland, i think we also have the longest one, at 2,600ft or 800meters. They're pretty cool to see, it's like human society has been gone for years and wildgrowth claimed the structure. Funnily though, i've never actually seen wildlife crossing these when i pass one of them, but they do work very well.
I had a friend who's older brother was coming home to visit and during hunting season he hit buck deer. It was so clean that they kept the antlers sold the fur and shared the meat with neighbors. All was legal too. The car was more damaged but his brother was fine.
My ex-girlfriend designed all of the new highway area near Jackson hole Wyoming. Had the highway, pedestrian path for bicycles as well, Avalanche area, and also wildlife crossings.
Me: "Why did the chicken not cross the road?" Practical Engineering: "He could walk on the animal pedestrian bridge." FYI I don't think you will ever find a chicken in the wild. They're usually in farms.
Eastern Montana along I94 has tall fences with the one way jumpouts to try and prevent deer and antelope from getting to the highway and funnelling off those that somehow manage to get there.
My mom hit a cow once on a mountain road. luckily she was uninjured but the guy that came around the bend afterwards wasn't as lucky. No idea if he survived but he was flown out in a helicopter.
seeing the washington crossing over i90 makes me so HAPPYYY i love seeing something from my state, and you can see what what animals use the crossing on the WSDOT facebook
I kinda wonder what it'd be like if one of these wildlife overpasses ends up not getting enough maintenance and collapses like our normal car bridges sometimes do. Although I guess trees and deer probably put less stress on the structure than regular car trips.
Neat info! I wrote my Bachelors thesis in environmental sciences about this kind of bridges. And how relevant they are ecologically and economically (insurances pay a loooot of money because of collisions)
Is a wire fence is mandatory for the US highways? In some European countries the wildlife repelling fences are mandatory for high-speed highways (not for national roads), so bigger animals (like deer, boars, etc,) cannot cross the highway in normal cases.
Here in the UK they are building a construction for bats to protect them from the new HS2 high speed rail, its going to cost about £110,000,000. A total waste of money, the bats will find somewhere I'm sure. Mind you the HS2 project is already wasting some £80B+ so another £110M is just a rounding error.
I have to think about how the German-German border separated families for more than 40 years. But also 40 years that separated deers and wild animals. Yes, the animals could stay in the restricted areas without being seen. But a border wall remains a wall. Today we find it on the border between Lithuania and Belarus or Finland and Russia. But also between the US and Mexico. Only the birds are free there.
I would love to see you do a video on the dam removals in Oregon and the near immediate return of salmon to their native habitat. That is an incredible story that has been documented by OPB but I am sure you would have a different perspective with the same or similar conclusion.
the thing is a lot of animals do not like to go under anything as in a tunnel is dark and so dangerous. So for those a tunnel does not work. so the road needs to go below the animal route.

So. Would the people who study this discipline be called "road scholars"?
After the highway department installed a couple wildlife crossings on hwy 97 in Oregon deer collisions went way down. Works great!
came here to say that it went down by over 80% per year, reducing call outs to police, ambulances, fire service, but also increased local business as less shut downs on the highway leading to less traffic congestion leading to less loss in revenue to the businesses in local townships
We've seen the same results in the netherlands, and also it's made the local wild life population boom
plus, they are usually quite pretty

You will always have unexpected (or expected) side effects when you change nature. Nature will adapt if you give it a chance.

I think one of the biggest difference is that animals can't read signs, while humans don't read signs. Either way, you have to engineer a bridge to be so obvious and intuitive that it won't be disused.
Road signs shouldnt be text, they should be logographs.
Driving licences should probably be harder to get.
@@anothersquid In the USA very much so.
The best wildlife bridge is essentially a tunnel
Humans are animals, except we think we are "smarter"

yeah, it didn't seem that big to me😅
I'm pretty sure the biggest one is in the Netherlands, so yeah this Los Angeles crossing is only the "largest in the world" if the "world" means "USA"
Americans call everything they make the biggest in the World, even, if it's not. They just don't care to research
@prywatne4733 world pretty much means the USA (and sometimes Canada) in USA😂😂😂

As a small scavenging mammal I appreciate these bridges.
As a predatory bird, me too

The first wildlife crossing bridge I ever saw is over I-75 in Florida. It's part of the Cross-Florida Greenway. In addition to facilitating animal movement, it also carries the Florida Trail.
Oooh now I know why those ramps exist in the nature area near me. To prevent animals from getting stuck on the wrong side of our fences
Engineering to help people and nature to better coexist is some of my favorite engineering.
I'm interested in what specific branch of engineering is in charge of wildlife bridges. Is it more civil engineering, or environmental engineering?
I think it would mostly be civil engineers working in collaboration with ecologists.
In Southern Africa, Underpasses are used so that wild animals don’t leap onto vehicles below.
Cool to see the Tobin bridge and to hear you’re near to SATX!
I've seen several unused rail bridges in my area (Madison and St. Claire counties, IL) reused as bicycle/nature bridges. A great idea.
I hit a deer back in June, cost was about 6k
I did get about 30 pounds of usable meat though. Most expensive steak I have ever had.
A5 Wagyu eat your heart out!
I am always on the lookout for fresh roadkill. It is in high demand for the premium mega fauna and the smaller species are usually inedible
In Germany you cannot keep the meat. The deer belongs to the local hunter responsible for that area. Just taking it would also be theft.
For anyone interested in learning more, the book Crossings by Ben Goldfarb is an amazing look into road ecology and covers a bunch of the topics in this video including the mountain lion P22!
It is an eye opening book. Humans have a massive impact
Wooohoooo!!!! Practical Engineering!!!!!!
I hit a deer 2 years ago and completely totaled my truck! I would love to see less people go through the same thing.
Cool video!

Humans do not own this planet. We share it with an infinite wealth of fascinating beings. Things like wildlife crossing are the least we can do.
The most powerful are the owners.
We literally own this planet, I own 2 acres of this planet, no animals allowed. Expect maybe dog.
If English is your first language and you didn’t emigrate from the developed world that is almost certainly not true. You can modify your land such than animals have a hard time but the cops aren’t gonna come out and arrest the frogs & squirrels for trespassing it doesn’t work that way.
And animal control will only come for actual nuisances or danger.
Also property tax & eminent domain, you don’t own that like you think you do.
* least we can do
Would predators just camp on the edges of the bridges? Seems like an easy lunch strategy.
That's something I've always wondered, but I couldn't find any research or publications that discussed it in detail.
Loved to learn that even animals avoid “back alleys” 10:15

Happy holidays to the Hillhouse family from the Frame family.
In Finland a study found out that only mammal using wildlife crossings was humans. However wildlife tunnels were found effective.
We call these an "ecoduct". I think it's a fitting name for it.
I think it all starts by reversing road entitlement: they are not in our way. We are in their way.
This goes for animals on the motorways and other big roads, as well as it does for people in the cities. But since most motorists are also pedestrians and cyclists at some point, the point that cars are more in the way of people than the reverse, is less difficult to grasp. So building infrastructure for animals to cross roads has some overlap with building city infrastructure that's good for people, instead of cars. I'm from The Netherlands btw.
I78 in New Jersey was actually one of the first roads in North America to use wildlife bridges, they were incorporated in the designed phase for the route in the 1980s. If you've ever driven the road you'll know just how striking and awesome these structures can be.
This is what I needed this morning!! New Practical Engineering!!
I hope you have a great day 😊
If they'd just get a license, they could use the roads, too. Problem solved.
But how will you teach coyotes and deers to drive if the coyote eats deers? Think about the insurance premium for the deer and the coyote
The lack of opposable thumbs is a large hurdle to operating heavy machinery
Watching the news it always seems like only terrible things are happening in the world, but the fact we're willing to invest time and real money in projects like this gives me some hope for humanity.
Lol my cousin often answers the phone with, "Road kill cafe. You kill it, we grill it."
i thought all wildlife overpasses were called ecoducts
It probably varies from country to country. In Sweden we call them faunapassage. I have heard the term ecoduct, though.
Thank you for being so awesome!

Sometime roads are useful for eliminating pest species, brush tail possum and hedgehogs in NZ.
In Western Australia, road kill can include kangaroos, camels, goats, deer etc, each decomposing heap will have a scavenger bird standing on top and other birds busy eating the maggots. The cane toad pest ends up as a small leather wallet after baking dry in the sun, these stick to the road for weeks. Most WA vehicles have "roo bars", heavy steel pipe framework in front to prevent the impacted animal coming thru the windscreen.

FYI I don't think you will ever find a chicken in the wild. They're usually in farms.
not a lie, i saw a woman (farm owner) chasing down her chicken on the road in our area.
You’ve obviously not been to Kauai, wild chickens are all over the place there, I’ve personally seen many crossing roads 😉

Chickens are direct descendants of the junglefowl and those definitely live in the wild.

Great video! The lengths we go to to accommodate cars is truly insane. At the end of the day, this is car infrastructure.
I kinda wonder what it'd be like if one of these wildlife overpasses ends up not getting enough maintenance and collapses like our normal car bridges sometimes do. Although I guess trees and deer probably put less stress on the structure than regular car trips.
4:58 I believe that is the DVP in Toronto looking south from the Overlea bridge
Looks like the Don Valley Parkway to me too, the tall brown colour lights poles matches the site.
In Germany all major freeways are fenced to eliminate wildlife collisions
Neat info!
I wrote my Bachelors thesis in environmental sciences about this kind of bridges. And how relevant they are ecologically and economically (insurances pay a loooot of money because of collisions)
Is a wire fence is mandatory for the US highways? In some European countries the wildlife repelling fences are mandatory for high-speed highways (not for national roads), so bigger animals (like deer, boars, etc,) cannot cross the highway in normal cases.
In Alaska the moose just slowly walk out into traffic and if people don't stop their car turns into a convertible.
Here in the UK they are building a construction for bats to protect them from the new HS2 high speed rail, its going to cost about £110,000,000. A total waste of money, the bats will find somewhere I'm sure. Mind you the HS2 project is already wasting some £80B+ so another £110M is just a rounding error.
That’s 13:46 adorable 😁
I have to think about how the German-German border separated families for more than 40 years. But also 40 years that separated deers and wild animals. Yes, the animals could stay in the restricted areas without being seen.
But a border wall remains a wall.
Today we find it on the border between Lithuania and Belarus
or Finland and Russia.
But also between the US and Mexico.
Only the birds are free there.
The effect of power lines on wildlife is also am interesting subject
I would love to see you do a video on the dam removals in Oregon and the near immediate return of salmon to their native habitat. That is an incredible story that has been documented by OPB but I am sure you would have a different perspective with the same or similar conclusion.
Better to give animals their own crossing than have wandering onto the highway to be hit my a car or truck.

Down and under seems better than up and over you would think
the thing is a lot of animals do not like to go under anything as in a tunnel is dark and so dangerous.
So for those a tunnel does not work. so the road needs to go below the animal route.
@sirBrouwer sure.....it just seems more likely that an animal could jump off where if it's under that can't happen
I've hit 3 deer in my 36 years of driving. The first died on impact, the 3rd was unharmed, and the 2nd had to be shot by the Iowa State Patrol.
5:51 and 5:58 those puns though 😂
animals will always try to cross the roads and so everything that helps them doing so without them or people getting hurt is a great idea.
As a motorcycle enthusiast, I fully approve of these structures!!
