Wildlife crossings—bridges and tunnels that reconnect fragmented habitats—are becoming increasingly common across the globe. These structures reduce vehicle collisions, protect vulnerable species, and support biodiversity by allowing animals safe passage across roads and highways.
- Wildlife crossings reduce animal-vehicle collisions and boost genetic diversity.
- Scientific research confirms animals regularly use crossing structures.
- Bipartisan support and public approval are helping expand crossing projects globally.
What happened
In recent years, the construction and funding of wildlife crossings have surged worldwide as more governments recognize their ecological and safety benefits. These structures, which include bridges and underpasses, reconnect habitats separated by busy roads, allowing animals of various sizes to move safely across human infrastructure. Author and journalist Ben Goldfarb, who chronicled these developments in his book Crossings, has observed the growing momentum for such projects in places like South America, North America, and Europe.
The evidence base supporting wildlife crossings has become overwhelming. Studies show that animals not only use these corridors frequently but also benefit from them by avoiding dangerous road encounters and increasing genetic diversity. This progress has led to broad political cooperation, including pending legislation in the United States aimed at making wildlife crossing programs permanent. Public opinion surveys reveal widespread enthusiasm for these initiatives, highlighting a shared desire to coexist more harmoniously with nature.
Why it feels good
Wildlife crossings serve as inspiring reminders that humans share the planet with diverse animal species requiring unfragmented habitats to thrive. Their large, eye-catching designs—such as highway overpasses draped with native vegetation—act like 'billboards for connectivity,' visually communicating our commitment to conservation. This tangible infrastructure allows people to see a direct, positive response to environmental challenges, fostering hope and connection.
Beyond their functional benefits, these crossings symbolize a shift toward more thoughtful coexistence with wildlife. They invite communities to recognize their role as stewards of the natural world while supporting vulnerable species. The collaborative efforts behind crossing projects—ranging from local conservation groups to national governments—create a shared sense of purpose that uplifts public morale and cultivates optimism about future conservation successes.
What to enjoy or watch next
Follow the expansion of wildlife crossings in your region or globally as new projects break ground and existing ones become models for innovative road ecology solutions. Many crossings highlight partnerships between scientists, governments, and local conservationists working to restore corridors for endangered species, such as linking forest fragments or protecting iconic animals like Brazil’s golden lion tamarins. Exploring stories and imagery of these crossings provides fascinating insights into how infrastructure can support wildlife.
Tune into podcasts, documentaries, or local presentations featuring experts like Ben Goldfarb and organizations involved in crossing initiatives. These platforms often share firsthand accounts, research findings, and updates on newly funded programs, helping deepen understanding and community engagement. As interest grows, expect to see more creative designs and broader policies that integrate wildlife crossings into sustainable development and transportation planning.
