The N25 Waterford Bypass toll bridge, which opened in October 2009, saw a 50% rise in Heavy Goods Vehicles over the period 2010-2014.
Some 175,000 HGVs passed through the plaza during its first full year in operation. Volumes have steadily increased since to the extent that 262,000 trucks used it in 2014.
John Deasy said: “You’ll get a different interpretation of the significance of these figures depending on who you ask. That the trend is upwards which seems to be somewhat encouraging, although the cause of the increase is debatable.”
He acknowledged that the extensive roadworks on the quay in Waterford in recent years may have been a factor in hauliers and other motorists opting to take the toll road instead.
