Around 50 truckers have mounted a demonstration on the new Kilcock-Kinnegad bypass to protest against the high tolls being levied on the road.
The truckers have been gathering at the toll booths on the motorway since 7am and are refusing to pay to get through.
More vehicles are expected to join the demonstration before it breaks up at 9am.
Trucks are currently being charged €6.20 to use the road, something the Irish Road Haulage Association says is unacceptable.
Gardaí had warned motorists to expect major disruption during this morning's protest, but the IRHA said its members were keeping to the inside lane and motorists were getting through without any difficulty.
