The Regional Highway Safety Plan is a joint venture between 19 local governments in four counties (Cochise, Graham, Greenlee, and Santa Cruz) seeking to reduce risk of death and serious injury on roadways. The 2018 plan was developed by Wood (Amec Foster Wheeler) in coordination with SEAGO and the Sierra Vista MPO.

Federal regulations require all states to have a Strategic Highway Safety Plan that provides a comprehensive framework for reducing fatalities and serious injuries on public roadways. Visit Arizona's SHSP website the latest information.
