Australia Highway Bridges Save 75 Animals Nightly

When Western Australia opened a massive new highway last year, critics worried it would become a death trap for local wildlife. Trail cameras just proved them wonderfully wrong.

The Bunman Wadandi Highway, a 27-kilometer stretch south of Perth, features something special: 45 wildlife corridors woven right into its design. Engineers built 19 rope bridges, 24 underpasses, and two land bridges specifically for kangaroos, possums, and other native animals to cross safely.

Animal rescuers initially doubted the design would work. They feared the new highway would hurt more wildlife than it helped, despite the elaborate safety features.

New data released by the West Australian Department of Transport tells a different story. Motion-sensor cameras installed in April captured almost 1,000 images of possums and endangered brush-tailed phascogales using the structures across just 12 nights. That's more than 75 recorded crossings every single night.

"Monitoring to date has far exceeded our expectations and has shown regular and widespread use of the structures," a government spokesperson told the Australian Broadcasting Corporation. The cameras captured endangered western ringtail possums and other vulnerable species confidently using the bridges and tunnels.

Local conservationists remain cautious but hopeful. Manda Page, CEO of South West NRM, called the project "a great experiment" and said she looks forward to diving deeper into the data when the government releases its full technical paper.

The Ripple Effect: Wildlife crossings are proving their worth worldwide. Research shows these corridors can reduce wildlife vehicle crashes by more than 90 percent. In the United States, over 1,000 dedicated wildlife crossings now protect migrating animals, with states like Colorado and Arizona reporting major reductions in collisions.

One wildlife crossing can prevent about 1,400 accidents over its 70-year lifespan, according to Pew Research Center. That translates into billions of dollars saved in medical costs, property damage, and lives preserved, both human and animal.

California is preparing to open the world's largest wildlife corridor, which has already attracted mule deer before construction finished. Malaysia and other parts of Australia have also embraced the concept, proving that roads and nature don't have to be enemies.

The Australian highway's success shows that thoughtful design can protect endangered species while supporting human transportation needs, creating wins for everyone who shares the land.
