Yes. 80-97% reduction in vehicle-animal collisions, per: https://www.sciencedirect.com/science/article/abs/pii/S00063...

> If wildlife fencing and crossing structures are designed based on the requirements of the target species, and if they are implemented and maintained correctly, the measures can reduce large mammal–vehicle collisions by 80–97% (Clevenger et al., 2001, Gagnon et al., 2015, Sawyer et al., 2012).
