The proposed project is located in Cochise County, along Interstate 10, between mileposts 345.50 and 356.49, near Willcox. The work includes milling the existing asphaltic concrete surface course and replacing it with new asphaltic concrete and a stone matrix asphaltic concrete overlay. It also involves replacing guardrails and guardrail end terminals, repairing existing bridge decks and concrete box culverts, updating pavement markings, and performing other related work.
