SR 90 – Pavement Rehabilitation, Kartchner Caverns to Camino De Pampas

State Route (SR) 90 is a four-lane divided highway which serves as a north-south link between Interstate 10, SR 82, the cities of Benson and Sierra Vista, Fort Huachuca, and Kartchner Caverns State Park.  The roadway was degraded asphalt with striping, reflective pavement markings, and rumble strips on both shoulders.  The purpose of the project was to extend the life of the pavement and improve safety of the roadway by repaving within the project limits.  Per ADOT standards, DSG completed agency scoping, hazardous materials review and a biological review for the project.
