The primary purpose of this study is to determine what transportation improvements would be needed to accommodate future growth and development of the Raytheon Missile Systems facility located south of Tucson International Airport on Hermans Road. A secondary purpose of this study is to consider longer-term roadway and transit improvements that will improve access to Tucson International Airport and associated airport property planned for future development. Specifically, the study analyzed the effects of closing Hughes Access Road/Alvernon Way to non-Raytheon traffic and recommends alternative roadway improvements that would be needed to accommodate this closure.
