Around 150,000 passengers are hoping to travel on the Holyhead to Dublin route in the days leading up to Christmas
The Government is "ramping up" public transport to meet rerouted passengers because of Holyhead's port closure.
Ferry ticket holders have been encouraged to rebook for alternative routes as its is unknown when the port, which closed due to damage caused by Storm Darragh, will reopen.
Around 150,000 passengers are hoping to travel on the Holyhead to Dublin route in the days leading up to Christmas.
Junior Transport Minister and Kildare North TD James Lawless met with the Welsh Cabinet Secretary for Transport yesterday to discuss how many shipping containers are still at the port and how many passengers are affected by the closure.
He is today meeting with stakeholders, such as Irish Rail and the Irish Road Haulage Association (IRHA) this morning before meeting representatives of ferry companies Stena and Irish Ferries this afternoon.
Wales has agreed to relax rules on driving times for hauliers to help reduce the backlog of freight.
Mr Lawless said he has signed a derogation to the rules which will be in place for 14 days.
The Minister said he is trying to organise which transport links will be available to people.
