Stay Informed

The State Route 347 Improvement Project will improve a 14-mile section of SR 347 between Interstate 10 and the City of Maricopa. This project corridor runs through Maricopa and Pinal counties and is primarily located within the Gila River Indian Community.

The planned improvements include:

Adding one lane in each direction along SR 347 from I-10 to the City of Maricopa
Rehabilitating the existing pavement along that same 14-mile stretch of roadway
Constructing new grade-separated interchanges at Riggs Road and Mammoth Way
Adding turn lanes and other intersection improvements at Casa Blanca Road and Maricopa Road

Once complete, the SR 347 Improvement Project will provide added capacity, help alleviate congestion, and improve safety and traffic flow along this busy stretch of roadway that drivers depend on every day.

Construction on the SR 347 Improvement Project is now underway. The first phase, the pavement rehabilitation of the 14-mile project corridor, began in late June. The entire improvement project with all of the upgrades will take approximately three and a half years to complete and is scheduled to be finished by the end of 2029.

Public Involvement

ADOT and its project partners held two in-person meetings in August 2024 to present and seek input on proposed improvements to the Riggs Road traffic interchange at SR 347, as well as the SR 347 corridor widening project. These two projects are now part of the SR 347 Improvement Project.

The 2024 public meetings were held in the City of Maricopa and the Gila River Indian Community to provide an opportunity for community members to provide their input and ask questions about the projects.
