Evaluation of Measures to Minimize Wildlife-Vehicle Collisions and Maintain Wildlife Permeability Across Highways: Arizona Route 260

We conducted wildlife-highway relationships research from 2002–2006 along a 17-mile stretch of State
Route 260 in Arizona which is being reconstructed in five phases with 11 wildlife underpasses and 6
bridges. Reconstruction phasing allowed us to use a before-after-control experimental approach in our
research.
