Many of our busy national highways cut deep through forests. Animals that cross these roads may sometimes get run over by fast-moving vehicles. To avoid this, the National Highways Authority of India (NHAI) has built nine dedicated underpasses for wildlife on the national highway NH47 that passes through the Kanha-Pench forest belt.
The cameras installed in the underpasses have revealed that a number of wild animals use them. The animals, including tigers, used the underpasses mostly at night to cross over to the other side of the forest. While some stayed back to take a nap or to have some fun with their playmates, a few others prowled the dark underpasses hoping for a good catch!
The concept was first developed in France in the 1950s. It took off in the Netherlands, where more than 600 crossings have been constructed to protect badgers, elk and other mammals. The Dutch built the world’s longest animal crossing, the Natuurbrug Zanderij Crailoo, an overpass that spans more than 0.8 kilometers (0.5 miles). Wildlife crossings can also be found in Australia, Canada and other parts of the world. The idea took a little longer to catch on in the United States, but wildlife bridges and tunnels began appearing there in the 21st century.
