The lorry was close to the Dunsilly roundabout slip when the incident happened on the Ballymena Road.
The PSNI, Northern Ireland Fire and Rescue Service and Northern Ireland Ambulance Service are all at the scene.
A PSNI spokesperson said: “The Ballymena Road in Antrim is closed in both directions at the Dunsilly Roundabout off slip due to an overturned lorry. Please seek an alternative route.”
