Data recorded by Transport Ireland via a traffic counter at the Bridgend border crossing revealed that in 2018 a daily average of almost 9,000 vehicles crossed over in either direction. The N13 accounts for 11 per cent of daily total cross border vehicle movements.
Also, 7.5 per cent of this traffic volume on the N13 road between Derry and Buncrana consisted of goods vehicles.
In 2018, an average of 666 goods vehicles crossed the border at Bridgend each day. Broken down, the figures show 109 rigid goods vehicles, 98 articulated lorries, and 459 light goods vehicles crossed over from Derry each day.
Seamus Leheny, policy manager at the Northern Ireland Freight Transport Association whose organisation collate traffic data from various sources has said that a no-deal Brexit is "now a tangible threat" and businesses must prepare for that.
He added:"Brexit will undoubtedly be the major influencing factor for the logistics and freight industry in 2019. This is simply down to the reason that any sudden changes to market conditions will overnight undermine supply chains that are incredibly sensitive to tariffs, regulatory controls and routes.
"A no-deal unhinge the UK economy but we in Northern Ireland would suffer the brunt of this due to our reliance on intermediate goods from the Republic."
