The concrete pour for the quarter-mile-long eastbound I-10 bridge deck, part of Arizona’s $1 billion rehabilitation of the Wild Horse Pass Corridor, has been completed, according to the state Department of Transportation.
The 1,350-cubic-yard pour took about a month to finish the second half of the new bridge over the Gila River. The final span now measures 62 feet and weighs 2,734 tons or the equivalent of 135 fully loaded concrete trucks.
Work on replacing the 60-year-old eastbound and westbound bridges over the Gila River began in May 2024 and is set for completion in October. Upcoming work on the corridor includes building the approach slabs on both ends of the completed eastbound bridge, as well as the deck joints and barriers.
This latest bridge deck pour represents the first of four contracts comprising the overarching I-10 Wild Horse Pass Corridor Project, scheduled to be fully completed by late 2029.
The full I-10 Wild Horse Pass Corridor will run 26 miles from the Loop 202 Santan/South Mountain Freeway to just north of Casa Grande, adding travel capacity, new interchanges, new crossroads and updated infrastructure to the interstate.
The $284 million second phase recently began to widen the highway from two to three lanes in both directions for 10 miles. The corridor runs north and south between Phoenix and Casa Grande in southern Arizona, beginning at Gas Line Road and ending south of State Route 387.
Powered byThe $470 million third leg will widen 11 miles of I-10 in both directions from the Loop 202 Santan/South Mountain Freeway to the I-10 Gila River bridges. The $158 million fourth and final phase will begin later this year and cover three miles of I-10 between the Gila River and Gas Line Road.
