These are animal crossings, designed to reduce vehicle-animal collisions. First introduced in the Netherlands, these bridges have caught on globally and are slowly being introduced by countries that see the benefits of preserving wildlife. This is not only beneficial from an ecological point of view, but also from a financial point of view. The costs of damages incurred in a collision along with roadway cleanup and emergency response is astronomical (in the billions, actually). Even if those benefits don't seem important to you, most of these crossings are quite beautiful
