Two men who were in the car, aged in their 30s and 40s, were arrested at the scene.
During the course of a follow-up operation at a residence on the Tullow Road in County Carlow at approximately 3pm, gardaí searched a vehicle on the property and approximately €200,000 of suspected cannabis was located within a concealed compartment and seized.
The investigation is part of Operation Tara, focussed on tackling drug trafficking networks at all levels.
All of the drugs seized will be sent to Forensic Science Ireland for analysis.
Both men have since been charged and are expected to appear before Ennis District Court on Monday, August 8, at 10.30am.
