As the impact of Brexit continues affecting trade, lorry freight volumes on ferries between Dublin and Holyhead – the busiest Irish Sea route – fell by a third in the first nine months of the year.

New industry figures to be published shortly will show a sharp reduction in the number of lorries moving between Ireland and Britain and across the “landbridge” to mainland Europe as companies prefer the certainty of direct routes without border checks and controls.

The Irish Maritime Development Office is finalising figures on port traffic for the third quarter.

Dublin Port and Rosslare Europort have recorded sharp declines in lorry freight traffic between Ireland and Britain but a surge in freight volumes on direct routes as traders avoid post-Brexit Britain.

There has been an increase in lorry freight moving on ferries between Northern Ireland and Britain as hauliers move away from ports in the Republic to avoid checks on goods.

Neither Dublin or Rosslare have experienced the disruption to shipping witnessed in the UK where shipping companies have had to divert supersized cargo vessels away from Britain because of bottlenecks in the global supply chain and a shortage of lorry drivers.
