CONSTRUCTION - AZ BLM 93(1) Monolith Garden Trailhead

This project will be advertised under full and open (unrestricted) competition. PROJECT DETAILS This project will consist of bridge deck replacement on project AZ BOR CIBR 900(1), located approximately 25 miles south of Blythe California, in La Paz County, AZ. This project also consists of 1800 ft of widening on southbound US 93 on AZ BLM 93(1), Monolith Gardens Trailhead and Turnout, in Mohave County, Arizona. The estimated price range for both projects is between $1,500,000 and $2,500,000. Lower Cibola Bridge Deck Replacement: The Lower Cibola Bridge is located approximately 25 miles south of Blythe California, and approximately 100 miles north of Yuma, AZ. The bridge spans across the Colorado River at River Mile 93.6 and is approximately 557 feet in length. The bridge is wholly located in Arizona and within the Cibola National Wildlife Refuge. The project is for a deck replacement of the existing Lower Cibola Bridge. Minor work included with the deck replacement are: replacement of the existing curb and railing across the bridge, paving approximately 100 feet of the approaches to the bridge, guardrail installation at the bridge approaches, removal of road closure gates, replacement of navigation lighting, installation of minor conduit, and jacketing the timber piles of the bridge. There will be no substructure work other than the pile jacketing. The deck replacement will require the removal of the concrete deck, the steel railing, and existing minor conduit. The removal of the deck will be tightly controlled; no explosives will be allowed or any heavy equipment to remove the slabs. Deck removal will be by concrete saws and pneumatic or electric hammers of limited weights. No debris will be allowed into the river. The Colorado River is a navigable waterway, and close coordination with the US Coast Guard will be required during construction. It is anticipated approximately 400 cuyds of concrete will be required for this project, approximately 100 tons of asphalt, approximately 1200 feet of steel bridge railing, approximately 400 feet of guardrail, approximately 200 feet of pile jacketing, and over 1100 feet of conduit. There is minor earthwork for installation of guardrail, approach road tie-ins, and general road reconditioning. Minor turf establishment will be required for all disturbances as a result of the construction. The bridge will be closed during construction, however minor traffic control will be required. Pile jacketing will require an in depth underwater inspection of the piles and documented for the pile encapsulation. Underwater inspectors will be certified by the National Bridge Inspection Standards (NBIS) and will furnish all equipment, labor, licenses, permits, and insurance necessary to perform and complete the work. Only a small percentage of pile encapsulation is anticipated, however and option will be included for all pile encapsulation should funding be available. Monolith Gardens: The Monolith Gardens project consists of constructing approximately 1800 feet of acceleration and deceleration lane widening on southbound US 93 near milepost 69, approximately 3 miles northwest of Kingman Arizona. The project also consists of reconstruction of the access to the BLM Monolith Gardens trailhead. Principle work items include: 400 tons of asphalt pavement, 650 tons of aggregate base, 60 tons of asphalt friction course, 1,500 square yards of pavement milling, 200 cubic yards of roadway excavation, 750 feet of guardrail, and 1 cattle guard and metal gate.
