U.S. Steel broke ground Oct. 30 on a $1.9 billion direct-reduced iron plant at Big River Steel Works in Osceola, Arkansas.
-
The facility will connect Minnesota iron-ore production with Arkansas electric-arc furnaces and could support 2,000 construction jobs at peak.
-
Preliminary site work is underway, with construction expected to begin later in 2026, the company said.
U.S. Steel broke ground Oct. 30 on a $1.9 billion direct-reduced iron steel plant, or DRI, at its Big River Steel Works campus in Osceola, Arkansas.
The facility will connect the company’s Minnesota iron-ore production with electric-arc furnace steelmaking in Arkansas. "The mine to mill connection supports next generation steelmaking and a robust American supply chain," US Steel said.
Preliminary site preparation is underway, according to a company announcement.

"First-of-its-kind" Facility to Feed Electric-Arc Furnaces
Direct-reduced iron, DRI, is made by removing oxygen from iron ore without melting it. It is used as an input to steel manufacturing. The iron stays solid rather than melting, leaving a porous material called sponge iron.
U.S. Steel said its 'first-of-its-kind production facility' using DRI material can replace prime scrap. The material is fed hot into the Big River 2 electric-arc furnaces, supporting the company’s lower-emissions steelmaking strategy.
The company estimates the project will create about 200 full-time jobs and 2,000 construction jobs at peak.
The Big River campus has four electric-arc furnaces and produces more than 6 million tons of steel annually, the company said.
Aluminum and Steel Post Double-Digit Inflation Over the Past Year
The impact on the American steel market from the new US Steel direct-reduced iron steel plant may be years away, but the potential for raising domestic production capacity is a welcome sign amid rising metal prices.
The news comes as two key energy-intensive construction materials, aluminum and steel, have both posted double-digit inflation over the past year, according to ConstructConnect Associate Economist Devin Bell. The economist reported last month that:
-
The Producer Price Index (PPI) for steel mill products rose 27.6% year over year in September, the fastest pace since May 2022.
-
Inflation for aluminum mill products peaked at 53.6% in June before cooling to 25.2% in September.
Bell added that, "Importantly, steel and aluminum imports have faced 50% tariffs since June 2025, limiting how much foreign supply can offset higher domestic prices."

U.S. Steel expects construction to begin in the latter part of 2026. The US Steel announcement does not provide a detailed construction sequence.
ConstructConnect News reported Oct. 27 that the company’s board approved full funding for a nearly $3 billion hot-strip mill at the Edgar Thomson Plant near Pittsburgh. That project is separate, and U.S. Steel said construction there will begin after permits, with initial production targeted for late 2029.
