Colorado residents and over 80 million visitors annually are drawn to the state’s scenic opportunities and abundant wildlife. As the population of Colorado grows rapidly, the accompanying development puts great pressure on the healthy wildlife populations of the state. Scientists, managers, and numerous stakeholders concerned with the effects of this growth on wildlife have long been pushing for the protection of wildlife habitat, including key movement corridors. Keenly aware of public support for protecting wildlife corridors, lawmakers in Colorado have been on the leading edge of developing connectivity related policies at the state level.
The following policies have set in motion a series of projects intended to maintain or improve the ability of migratory species to move freely throughout the state. The goal is for wildlife to safely cross the network of roads throughout their ranges through a series of overpasses, underpasses, and fencing installations. Currently, there are 16 underpass and 3 overpass structures built or planned across 5 significant project areas. These structures, coupled with road signs, widened lanes and shoulders, and maintenance of tight curves in the road, not only allow wildlife to move more safely between habitat patches but also increase safety for drivers.
