U.S. Customs and Border Protection officers nabbed a man, 60, with almost 160 pounds of pot.
CBP says the bust happened Monday night at the Calexico downtown port of entry.
Officers lifted the hood of the driver's pick up and found seven wrapped packages of marijuana.
There were additional packages in other parts of the truck.
The drugs have an estimated street value of more than $94,000.
The Mexican citizen arrested is behind bars at the Imperial County Jail.
