About ADOT . The ADOT highway corridors pass through 13 distinct life zones with elevation ranges of 300 to 10,000 feet. The larger species such as black bear, elk, deer and bighorn sheep are obvious hazards to motorists traveling at highway speeds, especially when dense roadside vegetation allows them to approach the roadway unseen by drivers. Motorists with advanced warning and a clear view of the surroundings are better able to make safe decisions than wildlife acting on instinct. Some of the intermediate sized animals such as turkey, coyotes, javalina and Coues deer can upset subcompact vehicles traveling at speed or do significant damage to larger vehicles.
Accidents caused by loss of control of the vehicle due to avoidance manoeuvers are also a factor.
Participate in project management teams and assist in the location of highway structures in topography that encourages wildlife to cross in drainages and arroyos under highway structures by using features such as enlarged culverts and wildlife-friendly bridges.
