Donaldsonville, Louisiana — Hyundai Steel and its partners officially broke ground Friday on a massive $5.8 billion low-carbon steel mill along the west bank of the Mississippi River. The milestone event marks a critical step toward establishing a robust, made-in-America automotive steel supply chain for the region.
The groundbreaking ceremony, held on Sept. 4, 2026, brought together high-ranking executives from Hyundai Motor Group, POSCO, and government officials from both South Korea and the United States. Located roughly 40 miles south of Baton Rouge in the Modeste area of Ascension Parish, the upcoming facility is slated to become operational in 2029, according to company officials.
As industrial investments reshape the U.S. South, the massive $5.8 billion Hyundai-POSCO Louisiana Steel project underscores a strategic shift for foreign automakers seeking localized production bases amid tighter trade barriers and import restrictions.
Project Ownership and Operational Scope
Operating under the entity Hyundai-POSCO Louisiana Steel, or HPLS, the ambitious venture features a multi-company ownership structure designed to secure the automotive supply chain. Hyundai Steel holds a 50 percent stake, POSCO owns 20 percent, and Hyundai Motor and Kia each hold 15 percent, giving Hyundai Motor Group companies a combined 80 percent control over the project.
When completed, the facility will occupy approximately 1,822 acres near Donaldsonville, providing direct access to deep-water ports, major interstate highways, and railroad networks. Company officials report that the mill will possess an annual production capacity of 2.7 million tons of hot-rolled, cold-rolled, and coated steel products. While full-scale construction is slated to kick off in the fourth quarter, groundwork, clearing, and drainage have already progressed steadily since March.
Economic Impact and Environmental Commitments
State officials have heavily praised the influx of capital and the projected employment opportunities tied to the venture. Louisiana Economic Development previously projected that the mill will generate more than 1,300 direct jobs alongside 4,100 indirect positions, totaling roughly 5,400 regional opportunities. Company CEO Hyung Jin Kim noted that the direct positions will carry an average annual salary of about $95,000.
During the groundbreaking event, Louisiana Gov. Jeff Landry emphasized the alignment of the project with national manufacturing goals. “Under President Trump’s America First agenda, we are reshoring manufacturing jobs here in America,” Landry said, recalling a conversation with President Donald Trump following the finalization of the deal. U.S. Reps. Julia Letlow and Troy Carter, LED Secretary Susan B. Bourgeois, and South Korean Industry Minister Kim Jung-kwan also participated in the ceremonies.
Designed to reduce environmental footprints, the plant will utilize natural gas in its iron-reduction process alongside electric-arc furnaces. According to state economic officials, this method will cut carbon dioxide emissions by an estimated 70 percent compared to conventional blast furnaces. South Korea’s Ministry of Trade, Industry and Resources noted that clean hydrogen could eventually replace natural gas as technology matures.
Community Engagement and Regulatory Review
The milestone groundbreaking follows a period of intense local scrutiny regarding environmental permits. The project concluded a week that featured a lengthy Louisiana Department of Environmental Quality public hearing at the Lemann Memorial Center in Donaldsonville regarding the facility’s air permit.
The hearing drew a large crowd consisting of both supporters and vocal critics, including members of local advocacy groups such as the Louisiana Bucket Brigade, Good Neighbors Louisiana, and Rural Roots Louisiana. Opponents raised ongoing concerns regarding community impacts, labor matters, and localized environmental effects.
Looking Ahead
With site preparation well underway and the formal groundbreaking complete, HPLS moves into its next operational phase as fourth-quarter heavy construction approaches. Observers and regional leaders will closely monitor construction milestones as the project targets its scheduled 2029 operational launch.
