This project comprised of designing a new two-lane roadway from SR-79 to Sandman Road, approximately 6.5 miles, to provide access to a proposed landfill site. This project involved the evaluation of using different side slope grades and barrier protection to reduce construction cost. Grades near the landfill were particularly steep and were lessened to comply with jurisdictional requirements and to address concern of heavy vehicles driving on steep grades and their impact to other road users. The improvements also included four drainage crossings and intersection improvements at the SR-79 / Cottonwood Canyon Road intersection.
Location: SR-79 to Sandman Road, Pinal County, AZ
