Ferry operator Stena Line has announced a new sailing route from Dublin to Cherbourg in France.
The once-weekly route, which will begin next Saturday, aims to give hauliers an additional option to bypass Britain following Brexit.
The company says there has been a change to the flow of freight on the Irish Sea, with its services to Holyhead down around 60% in the first two weeks of this year.
Meanwhile, around a quarter of hauliers arriving into Dublin Port from the UK are believed to be experiencing problems at customs checks.
There are reports the new Brexit requirements are resulting in food consignments getting blocked in UK warehouses or stopped at Irish ports.
The Road Haulage Association says it has led to some deliveries having to be dumped and empty supermarket shelves.
