Fauna underpasses are structures that have roads that allow the movement of animals without the danger of being run over.

In order to evaluate the efficiency of the fauna underpasses installed in the SP-55 highway, were made to verify traces two installments of sand at their ends. During 49 days the species that used the fauna underpasses were checked. Traces of lizard found in a small mammal besides human remains and domestic dog. Interviews with residents raised more than 40 wild species present in fragments side of the road.
