New analysis reveals the 20 most treacherous roads in Ireland

Eight of the 20 stretches of road on the list are located in Galway.

A stretch of road from Clifden to Leenaun in west Galway is the most treacherous in the country, according to analysis by a location intelligences services provider.

According to Gamma Location Intelligence, which provides location-based insights to insurance companies and local authorities in Ireland, the N59 between Clifden and Leenaun is the most treacherous in the country.

The N59, in fact, appears nine times on the list of the most dangerous stretches of roads, both in Galway and in Mayo.

The road between Abbey Square Roundabout and Seamus Rafter Bridge in Enniscorthy in Wexford is the second most treacherous road, while the third is at the Killashee Street, Ballymahon Street and New Street junction in Longford town.

The analysis is derived from data from Transport Infrastructure Ireland (TII) from 2015 to 2017 which shows the roads with the highest collision rates (injury collisions per 100 million vehicle kilometres).

The data is restricted to motorway and national roads only; a vehicle kilometre is based on the number of vehicles using the road segment and its length.

Eight of the roads ranked as the 20 most treacherous are located in Galway, four are in Clare, with two apiece in Cork and Mayo.

Speaking about the data, Director of Location Intelligence for Gamma, Richard Garry, said: “Overall, according to the data provided by Transport Infrastructure Ireland, collision rates are decreasing across the country. However, there are specific stretches of roads where the frequency of collisions is still high.

“Not only does this analysis show drivers where they need to take extra care, it is also useful for insurance companies as it identifies the areas which are worst for road accidents and enables them to better assess risk.”
