This versatile 8,000 SF metal warehouse offers a rare combination of modern construction, multi-bay flexibility, and immediate interstate access — all at an exceptional value. Built in 2019 and recently renovated in 2026, the building features ten 12’x14' overhead doors with automatic openers, 16' clear-span ceilings, and reinforced concrete floors. Each 16’x50' bay includes framed demising walls with pass-through service doors, giving an investor or owner-user the option to operate individual bays, lease them separately, or open the entire 8,000 SF for single-tenant use. Sitting on a full acre just 500 feet from I-270, this property is priced to move. 5400 Old Alton Road is located in one of the Metro East’s most accessible industrial corridors, just 500 feet from the I-270 eastbound and westbound ramps. The property offers quick access to the St. Louis metro area, making it a strong fit for contractors, distributors, and service businesses serving customers in both Illinois and Missouri. Nearby users include Amazon, Gateway TradePort, Flying J, Heartland Express, and Gateway Commerce Center, reinforcing the area’s established freight and industrial presence.
