SR 347 Corridor Widening, I-10 to city of Maricopa
SR 347 Corridor Widening, I-10 to city of Maricopa
Overview
The Arizona Department of Transportation, in partnership with the Gila River Indian Community and Maricopa Association of Governments, is proposing to construct improvements along SR 347, between Interstate 10 (I-10) and the northern limits of the city of Maricopa.
Project Elements
The project team will evaluate:
- Widening SR 347 by one lane in each direction, primarily toward the median (or outside – where required) from the city of Maricopa Limits (MP 175.7) to I-10 (MP 189.1).
- Widening existing bridges at Santa Rosa Wash, Santa Cruz Wash and Gila River.
- Extending box/pipe culverts as needed.
- Intersection improvements at Casa Blanca Road, Borgia Road (Sacate Road), Mammoth Way (Cement Plant Access Road) and Old Maricopa Road to accommodate a six lane highway.
- Casa Blanca Road and Mammoth Way Intersections: Additional modifications to improve traffic flow and safety are planned at these two intersections. (These improvements will take place on a different timeline than the other project elements.)
Project Area
Design Schedule
The corridor widening is currently in design and is expected to take two years to complete. It is not currently funded for construction. If funding becomes available, it is expected to advertise for construction in summer 2025.
The intersection improvement project for the Casa Blanca Road and Mammoth Way (Cement Plant Access Road) intersections is funded for construction. Design is underway and it is anticipated to advertise for construction in spring 2025.
Public Input
The public will have an opportunity to provide input. Information on public involvement opportunities will be posted to the website once they are finalized.
