Gwinnett County police Cpl. Jake Smith tells WSB Radio that the operation known as "South Surge" is in response to an increase in crime in the department's south precinct.
The operation, which began Aug. 18, has involved several police check points around county roadways. Police say 65 of the arrests have been for felony offences.
The most recent checkpoint along Ronald Reagan Parkway in Lawrenceville Wednesday night resulted in several arrests of suspects on charges such as drunken driving and drug possession.
Gwinnett County is just northeast of Atlanta.
