The project involves replacing an existing concrete ford crossing at the Canada del Oro Wash within Catalina State Park, located adjacent to State Route 77 in Pima County near Tucson, with a seven-span cast-in-place reinforced concrete closed frame bridge. The scope includes reconstructing the entrance road approaches to seamlessly connect with the new bridge structure and ensure proper alignment with intersecting park roads. Additional work encompasses channel grading, bank restoration, and the removal and stockpiling of excess wash materials to restore natural waterway conditions. The site begins 2000 feet northeast of the park entrance station and requires careful coordination to minimize environmental disruption while maintaining access during construction. The solicitation, identified as Call 027 2023027, was posted by the Arizona Department of Transportation with a response deadline of August 14, 2026. It is categorized under a state-level transportation project with no specified set-aside type and falls under the purview of Arizona’s infrastructure management. The work is located entirely within Pima County, Arizona, and is intended to improve public access and safety at a critical crossing point within the state park system. All activities must adhere to environmental and engineering standards to preserve the natural wash environment while providing a durable, high-capacity structure for park visitors and emergency services.
