Working list of wildlife overpasses worldwide – 2026 Update
Interstate 11 Wildlife Overpass – Boulder City, Nevada – Source: conteches.comThe following working list identifies wildlife overpasses, bridges, and ecoducts built across roadways, railways, canals, and highways around the globe. Other synonyms used to describe these structures include, but are not limited to:
- Animal bridges
- Eco-bridges
- Ecoducts
- Eco-links (in Singapore)
- Ecoponts or Écoduc (in France)
- Fauna bridges (in Australia)
- Fauna overpass (in Denmark)
- Green bridges (Grünbrücken in Germany)
- Land bridges
- Nature bridges
- Overcrossings
- Renoducts (for reindeer in Sweden)
- Rope fauna or rope canopy bridges
- Viaduto vegetados (in Brazil)
- Wildlife bridges
- Wildlife overpasses.
The term “Ecoduct” seem to have become the most commonly used term in Europe and can be defined as an arched viaduct (land bridge) for ecological uses such as wildlife. “Wildlife Overpass” tends to be most often used in North America.
The list does not include underpasses, tunnels, and similar structures for wildlife to use. In certain places, ecoducts are referred to as tunnels. Those that are actually ecoducts are included on this list. In addition, those green bridges in England that are primarily meant for farm animal movement have not been included.
Fauna Rope Bridge in Australia – Source: faunatech.com.auWildlife overpasses/ecoducts can now be found on every continent except Antarctica, with them now in existence in nearly 40 nations that are listed below. Some surprising nations where no ecoducts have been identified thus far include Italy, Japan, New Zealand, Norway, South Africa, and Taiwan. As this is a working list, any additions, corrections, or suggestions are most appreciated.
