Construction of a key interstate crossing in Arizona has reached another milestone as work progresses on replacing the I-10 bridges over the Gila River, a project designed to improve freight mobility and long-term transportation capacity between the Phoenix metropolitan area and southern Arizona. Pulice recently completed a significant bridge deck concrete placement that advances work on the new eastbound structure.
Pulice, a Flatiron Dragados company, completed a 430-cubic-yard concrete deck pour for the eastbound bridge spanning the Gila River in Pinal County, approximately 30 miles south of Phoenix. The placement was carried out during an overnight operation and finished in less than five hours.
The work represents Phase 3 of deck construction and moves the project closer to completion of the new bridge structure. Project teams coordinated field operations, quality control activities and concrete deliveries throughout the placement to maintain continuous production during the pour.
The Arizona Department of Transportation project is replacing the existing two-lane bridges over the Gila River with new three-lane bridges that include full-width shoulders. Construction also includes rebuilding the roadway approaches as three-lane facilities separated by a concrete median barrier.
The upgraded crossing incorporates deeper bridge foundations and a higher bridge profile intended to improve resilience at the river crossing while increasing roadway capacity along Interstate 10.
The overall project is scheduled for completion in late 2026.
The bridge replacement is part of the broader I-10 Wild Horse Pass Corridor improvement program, one of Arizona's major transportation initiatives supporting both commuter traffic and commercial freight movement.
For construction owners and transportation agencies, the project demonstrates continued investment in modernizing critical interstate infrastructure while increasing roadway capacity and improving the reliability of a heavily traveled corridor connecting the Phoenix region with Casa Grande and Tucson.
