The project involves replacing an existing concrete ford crossing at the Canada del Oro Wash within Catalina State Park near Tucson in Pima County, Arizona, with a seven-span cast-in-place reinforced concrete closed frame bridge. The work extends along the main entrance road of the park, starting 2000 feet northeast of the entrance station, and includes reconstructing the road approaches on both sides to seamlessly integrate with the new bridge structure. Connections to intersecting park roads will also be modified to ensure safe and functional traffic flow. Additional work encompasses channel grading, bank stabilization and restoration, and the removal and stockpiling of excess wash materials to mitigate environmental impacts and maintain natural hydrologic functions. The contract, identified as Call 027 2023027 under the NAICS code 237310, is issued by the Arizona Department of Transportation with a posted date and response deadline of August 14, 2026. The project is designated as a state, local, or educational government procurement and is located entirely within Arizona. All work must be performed at the specified location adjacent to State Route 77, with no alternative performance sites permitted. The solicitation is open for proposals through the ADOT portal, and all bidders must comply with the technical and logistical requirements outlined for the bridge construction and environmental restoration components.
