Gardaí have warned motorists in Dublin to expect major traffic disruption tomorrow as up to 600 truckers are expected to take part in a protest against the Heavy Goods Vehicles ban in Dublin city centre.

The protest, which is being organised by a new group called the Road Transport Association, will begin at 5am on the northbound and southbound lanes of the M50 and at Dublin Port.

The Road Transport Association say the HGV ban is forcing them to use an already overburdened M50.

They say the tolls, extra mileage and traffic congestion on the motorway means their costs are increasing while their productivity is decreasing.

An estimated 600 trucks will converge at three locations from 5am in the morning and begin moving 30 minutes later.

The first group will start at Finglas and will drive south on the M50 to the Ballymount exit before turning around and going towards the M1/M50 interchange.

The second group will also travel on the M50 from Citywest to M1/M50 interchange.

The third group will drive from the Point Depot to Dublin Port and back.

They say the protest will not stop until they get progress.

The AA say there could be delays of up to one hour on the M50 tomorrow and are advising motorists to leave early.
