FAQs

Frequently Asked Questions

Find answers to the most frequently asked questions about SR 347 and its funding.

When would the funds be available for the widening of the 347?

Please refer to the section about what's currently funded.

Will the widening of 347 actually help bring businesses here?

Yes, businesses that count on transportation, desire this road to be widened.

What happens if we don't get the funds needed for the 347?

The City of Maricopa, ADOT, MAG, Pinal County, GRIC, Maricopa County, along with State and Federal Legislature understand that this needs to be funded.

Why does the city continue to allow residential development when the 347 is so congested?

That is a very complex question. It's important to understand that AZ is a property owner rights state. A moratorium on residential development has significant requirements, one being that the city has control over the need for improvement. The City of Maricopa does not have control over SR347.

What happened from the funds collected from Prop 417?

Arizona Department of Revenue has passed the funds over to Pinal Regional Transportation Authority (PRTA) allowing them to determine how to return the funds to the businesses. The PRTA is currently in the process of determining this process.

When will the widening of the 347 be finished?

This is such a complex question. The residents of Maricopa will see smaller projects started and completed over the next 5-10 years (as seen on "What's Funded"). The rest will follow as progress with acquiring funding continues.

When will the widening of the 347 be started?

Unknown at this time.

Will the Riggs Rd overpass impact the widening of the 347?

No, the overpass can be completed separate from the widening. The widening + Riggs Rd overpass are both within the same design process.
