Autonomous quarry haulage at Lake Bridgeport
Heidelberg Materials reported more than 2 million tons hauled autonomously at its Texas quarry
Problem
Lake Bridgeport Quarry struggled to recruit skilled haul truck operators. Limestone still needed to move from the pit to the crusher.
Approach
After a neighboring quarry pilot in 2023, Heidelberg Materials deployed Pronto's Autonomous Haulage System on a mixed fleet at Lake Bridgeport. The system used cameras, sensors and AI to operate heavy equipment. In January 2026, the company reported 8 months of autonomous hauling.
Results
Takeaway
The deployment addressed operator shortages while retaining a mixed fleet of existing truck brands.
