The number of road vehicles crashing into rail bridges increased this year, according to Iarnród Éireann, with 95 bridge strikes in 2016.
This compared to 85 in the previous year.
The bridge at Carrick-on-Suir in Co Tipperary has been hit 19 times alone in the past four years.
Speaking on RTÉ News at One, Jane Cregan from Iarnród Éireann said thankfully none of the bridge strikes this year caused "major structural problems".
However, she said the issue is a worrying one due to the fact it is a major health and safety issue and also due to the disruption it causes both rail and road users.
Ms Cregan said the company are working with hauliers and local authorities to improve signage approaching restricted height bridges.
She also pointed out that information on all restricted height bridges are available online and urged people to "check your load and check your journey" before setting out.
