Limestone isn’t just a construction material—it’s the foundation beneath nearly every road, bridge, school, and hospital in Florida. Much of it starts in one place: Miami-Dade County. According to the 2025 Aggregates Industry Scorecard, natural aggregates like crushed stone and sand generate $171 billion in total U.S. economic output and support nearly 730,000 jobs nationwide. Florida plays a leading role in this industry, and Miami-Dade is at its center. Local quarries supply over half of the construction aggregates used statewide, including the limestone that forms the base of Florida’s 12,000+ miles of highways.

Beneath Miami-Dade’s landscape lies a resource essential to everyday life: limestone. Often overlooked, limestone plays a critical role in building Florida’s roads, bridges, schools, and hospitals, forming the backbone of the state’s infrastructure. The Lake Belt region supplies approximately half of Florida’s construction aggregates, processing nearly 50 million tons each year for concrete, asphalt, and cement—contributing $1 billion to the economy and helping keep construction costs among the lowest in the nation.
