Colorado Opens Massive Wildlife Bridge, Cutting Animal-Vehicle Crashes by 90%
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Colorado’s new Greenland Wildlife Overpass now allows animals to safely cross six lanes of Interstate 25, reconnecting 39,000 acres of habitat and reducing wildlife-vehicle collisions by up to 90 percent.
📈 One key stat: The new overpass is expected to cut wildlife-vehicle collisions along the corridor by up to 90 percent, dramatically improving safety for both animals and humans on one of Colorado’s busiest roads.
💬 One key quote: “State officials say the bridge is now the largest wildlife overpass in North America, stretching about 200 feet across, 209 feet long, and covering nearly an acre of habitat.“

1️⃣ The big picture: Colorado has unveiled North America’s largest wildlife crossing, the Greenland Wildlife Overpass, spanning six lanes of Interstate 25 between Denver and Colorado Springs. This 200-foot-wide structure creates a natural pathway for elk, deer, and other wildlife to safely cross one of the state’s busiest highways. By reconnecting nearly 39,000 acres of habitat that was previously divided by the road, the overpass addresses a serious safety issue in an area that once averaged about one wildlife collision per day. The $15 million project completes an 18-mile wildlife mitigation system that includes fencing and underpasses, creating a comprehensive solution to protect both animals and drivers.
2️⃣ Why is this good news: The wildlife overpass creates crucial habitat connectivity by linking 39,000 acres of protected land to more than a million acres of Pike National Forest. This connection allows animals to access larger migration corridors, find more food sources, and maintain genetic diversity through population mixing. For human drivers, the structure dramatically reduces the risk of dangerous and costly collisions with large animals like elk and deer. The design incorporates natural vegetation and gentle slopes, helping wildlife quickly adapt to using this safe crossing point. Beyond the immediate safety benefits, the overpass serves as a model for similar projects across North America, showing how transportation infrastructure can be adapted to work with rather than against natural ecosystems.
3️⃣ What’s next: Wildlife cameras will monitor how different species adapt to using the overpass, collecting data on crossing patterns and effectiveness. Conservation groups plan to study whether the reconnection of habitat leads to healthier animal populations and wider ranges. The success of this project will likely influence future wildlife crossing designs in Colorado and across other states with high rates of wildlife-vehicle collisions.
