Deep beneath Cleveland, Ohio, the Whiskey Island salt mine, owned by Cargill, is working overtime to meet surging demand for road salt. Located 1,800 feet under Lake Erie, the mine is one of the world's largest, producing up to 4 million tons annually.
Cargill spokesperson Emily Tangeman confirmed that teams have been working overtime since September due to early and persistent winter weather, which has driven demand across the industry. Many municipalities have already used up their typical winter salt reserves.
The mine, accessed from Whiskey Island near downtown Cleveland, opened in the 1960s. Salt is extracted year-round through drilling and blasting in tunnels formed from an ancient inland sea. Inside, a maze of caverns stretches for miles, dimly lit and filled with heavy machinery.
Maintenance superintendent George Campbell said operations are continuous, with downtime for essential repairs. Cargill is prioritising shipments to areas of greatest need as winter conditions persist, with frequent smaller storms increasing salt usage.
Cities like Boston, Bangor, and Ithaca have experienced their coldest seasons in over a decade. Campbell assured that decades of salt reserves remain, stating, "I think that we have enough reserves to continue to keep people working for a long time."
