SR 347 Improvement Project

The State Route 347 Improvement Project will improve a 15-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 15-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 scheduled to begin this summer and will take approximately three years to complete.
