The tunnel was built underneath one of the most dangerous stretches of Highway 17 for wildlife. In the past 10 years, more than 20 mountain lions and 95 deer have been hit and killed while crossing the stretch.
The hope is the tunnel will make driving Highway 17 safer for people too by reducing the risk of hitting an animal.
After the tunnel was completed early last year, a bobcat was caught on camera using it less than an hour after surveillance cameras were installed. Deer are using it oo.
But the main focus of the tunnel is to help mountain lions travel between habitats separated by the highway.
