Wildlife crossing is the umbrella term encompassing underpasses, overpasses, ecoducts, green bridges, amphibian/small mammal tunnels, and wildlife viaducts (Bank et al. 2002). All of these structures are designed to provide semi-natural corridors above and below roads so that animals can safely cross without endangering themselves and motorists ...
The bridge is meant to allow animals to circulate through and thrive in habitats that are fragmented by human development. [1] The crossing is particularly critical for the mountain lions of the Santa Monica Mountains, which have declined and become genetically isolated [2] because the Ventura Freeway prevents them from moving between the mountains and the Simi Hills to the north.
Combinations of footprints of different species provide clues about the interactions of those species. Even a set of footprints of a single animal gives important clues, as to whether it was bipedal or quadrupedal. In this way, it has been suggested that some pterosaurs, when on the ground, used their forelimbs in an unexpected quadrupedal action.

The tunnel of tarps are in place to contain old paint and the blasting material. Workers are giving the old bridge a thorough cleaning as part of a $33.5 million project to repaint the 1955-built ...
