The semi was loaded with approximately 40,000 pounds of beer, according to troopers.
Troopers said the semi was travelling east on I-70, when the driver allegedly fell asleep, lost control, drove up a guardrail and rolled over.
The driver, who is from Hollywood, Calif., was not injured, but was evaluated by medics at the scene for minor bumps and bruises.
A Bobcat was brought in to assist with the unloading the beer from the overturned trailer.
