Road hauliers are calling on Minister for Foreign Affairs Simon Coveney to seek to improve the passage of freight between Ireland and other EU member states.
The Irish Road Haulage Association issued the appeal on the second successive day of gridlock in the southern English port of Dover.
The association's president said the gridlock was not only on the British side of the channel and that they are monitoring the situation, but it could go on for three weeks.
Eugene Drennan said that there are between 20 and 30 Irish trucks stuck in Calais at the moment, as many as ten of which have been there for up to 24 hours now.
He said that Friday evenings are a quiet time in terms of exports for Ireland and goods that left here last night will be coming through Calais tonight and in the early hours of tomorrow morning. He said this is where there will be a bigger delay of Irish produce.
He said the situation will not be resolved quickly, and it has been happening annually since Brexit and there is a repetitive nature to it.
He said that this is "the practical face of the challenge that Irish hauliers have faced since Brexit because we are an island".
Mr Drennan said that there has not been enough concessions for Ireland's island status.
He said that there are other shipping routes and other lanes out of the UK that may be more expensive but the IRHA would advise passing those costs onto customers because hauliers cannot afford any more costs.
"Our advice would be to any haulier, or any Irish person travelling privately, to avoid Dover and avoid that southern corridor into France, it’s just too troublesome this time of year," he said.
On freight, he said there seemed to be an emphasis on car traffic and freight was being delayed heavily due to the increased nature of passport inspection and the sheer volume of private cars.
He said many Irish people do not realise the intensity of the movement in the UK and the big population moving at one time and as a result the roads are very busy, describing them as "log jammed".
Mr Drennan said that when you hit the port at normal times you would always have delays but now the delay is passport control, with freight left to one side.
He said that he would call on the Minister for Foreign Affairs and his department to do whatever they can in their power to try to get some sort of flow of freight, in particular Irish freight, because this is EU to EU, adding that Ireland should have some channels open to it within the agreement.
"It's heightened by Brexit, but more heightened by the decision by one side to have more passport controls and more security around that.
"As well there seems to be lack of personnel on the French side. Perhaps it’s just the regular amount of people but there is not enough to deal with this surge at this time of year but something must be done about freight for southern Irish registered trucks," he said.
