Before the new Terminal 1 opens later this year, people should plan for another round of construction-related traffic interruptions when driving in and out of the airport.

Construction workers at the San Diego International Airport’s Terminal 1 dug up a grenade Thursday, prompting a response from law enforcement. The grenade was old and inert, meaning it had been hollowed out as a training tool and did not have the potential to explode,

The incident did not impact the airport's operations since the ordnance did not have the capability to explode, the Port says.

San Diego International Airport construction workers discovered what they think is "an old, inert hand grenade" near Terminal 1, a Port of San Diego official said Thursday afternoon. Airport operations are proceeding normally as of right now,
