AI data center construction is reversing decades of industrial decline in America's interior, with freight activity surging in the Heartland as infrastructure build-out accelerates.

AI data center investment is hitting $20 billion every two weeks, compared with the Interstate Highway System's approximately $20 billion per year (adjusted for inflation) over 35 years. A standard 500-megawatt data center requires roughly 30,000 truckloads of concrete, structural steel, and copper; Meta's 'Prometheus' project in Ohio is designed as a one-gigawatt campus, and the Delta Gigasite in Utah aims for 10 gigawatts over the next decade.

Freight volumes are up roughly 11% this year, with the surge concentrated in industrial modes—flatbeds and railroads—moving raw materials from the Midwest and South. SONAR data shows coastal activity remains quiet while the middle of the country is experiencing a breakout in freight activity, reversing twenty years of goods flowing overwhelmingly from the coasts inward.

The U.S. Heartland is the most efficient place on Earth to produce energy-intensive goods because of abundant natural gas from the shale revolution and federal tax incentives with domestic content requirements steering procurement toward American manufacturers. In sectors like steel and plastics, energy can represent up to 38% of total production costs.
