A 49-year-old man has been convicted of careless driving after he admitted driving a truck-load of almost 250 pigs over a bridge which was built to sustain only a quarter of the truck's weight.

David Patterson from Fivemiletown, Co Tyrone, has been fined €300 after pleading guilty to the charge at Listowel District Court.

Ballinagar Bridge at Lixnaw in Co Kerry collapsed under the weight of the truck and around 50 of the pigs died.

The incident happened on 1 February 2007.

Ballinagar Bridge, a steel structure, was constructed in 1993 and spanned more than 30 metres. It was inspected by engineers and deemed structurally sound before the incident.

However, a 12-tonne weight limit was imposed and this was indicated in signs on approach roads to the bridge.

The bridge has not been replaced.
