Maricopa is investing heavily in long-term transportation infrastructure — and SR 347 is only one piece of a much bigger strategy.
Here’s what real estate investors in Pinal County need to know:
SR 347 Expansion
- Expansion to three lanes in each direction
- Two new overpasses:
- Riggs Road
- Cement Plant Road
- New flyover connection at I-10
- Double left-turn lanes from Casa Blanca onto SR 347
- Designed to reduce congestion and improve traffic flow
Funding Strategy
- Funded by a half-cent sales tax increase
- Creation of a transparent Commuting Corridors Fund
- $784,000 collected in the first month
- City planning to issue a $30 million revenue bond
- First payment to ADOT due June 1
- No expected impact to the city’s general budget
I-10 Widening
- New lanes and HOV lanes
- Bridge reconstructions
- New interchanges and flyovers
- Freeway management systems
- Direct impact on access to Maricopa via SR 347
I-11 (Future Truck Bypass)
- Currently delayed due to litigation
- Intended to reroute semis and heavy truck traffic away from Maricopa
- Would reduce road wear and improve local driving experience
- Creates faster connectivity to the West Valley
Green Road Loop (Long-Term Vision)
- Connects SR 347 to SR 238 around city limits
- Currently in 30% design phase
- Requires coordination with the Gila River Indian Community
- Intended to reduce future congestion bottlenecks
East-West Corridor & SR 238 Widening
- East-West Corridor at 90% design
- New bridge over railroad
- SR 238 widening expected to begin next fiscal year
- Critical for West Valley commuter access
Why This Matters for Investors
- Maricopa leadership acknowledges the danger of relying on a single transportation artery.
- The city is planning for 10, 20, and 30-year growth horizons.
- Infrastructure expansion supports:
- Increased housing demand
- Stronger rent growth stability
- Reduced commute friction
- Greater long-term property desirability
For single-family investors in Maricopa and Casa Grande, transportation access is one of the most powerful value drivers.
Infrastructure reduces friction.
Reduced friction increases migration.
Migration supports rent growth.
More access = more long-term appreciation stability.
