I-680 Wildlife Crossing

Primary tabs

Wildlife populations in the East Bay open spaces are isolated from the rest of nature by I-680. There are very few crossing structures under this interstate, none of which were built for wildlife. Nonetheless, wildlife use these structures to move between the East Bay open spaces and the rest of the world. Without this movement, these populations would be isolated and subject to extinction.
