The Arizona Department of Transportation (ADOT) reports that they have completed the new east and westbound I-10 bridges over the Gila River, located approximately 11 miles south of the Phoenix/Chandler area. This completes the first of four project segments of the I-10 Wild Horse Pass Corridor Project.
Crews began constructing the bridges in May 2024. This work included removing the previous bridges and constructing new, wider and higher bridges. The bridges now consist of three lanes in each direction with wider shoulders. The third lane will open once the the rest of the segments in the project are completed.
The second segment of the project began construction in January 2026 and runs along 10 miles of I-10 in both directions north of Casa Grande. The third segment recently began construction, running along I-10 in both directions for approximately 11 miles from the Phoenix/Chandler area down to the Gila River. Once all four segments of the project are complete in late 2029, there will be an additional travel lane in both directions between the Phoenix area and Casa Grande.
Additionally, several interchanges along the project corridor will be reconstructed. New interchanges will be constructed between the Wild Horse Pass Boulevard and SR 347/Queen Creek Road interchanges, and at Seed Farm Road. Crews will also add freeway cameras, digital overhead messaging boards and wrong-way detection systems to help increase motorist safety.
While crews are working to make improvements, the speed limit is reduced to 55 mph between Phoenix and Casa Grande.
