The N81, south of Poulaphouca Bridge, has been identified as Wicklow's worst accident black spot.
A new analysis by Gamma Location Intelligence, a location intelligence services provider, has identified the most treacherous motorway and national roads in Ireland.
The stretch of the N81, south of Poulaphouca Bridge, 1.8km north of the junction with R411, just east of Kildare border, was found to have a collision rate of 76 road accidents per 100 million vehicle kilometres. Collisions are limited to those that resulted in an injury on major roads from regional to motorway.
The analysis is based on a map of Transport Infrastructure Ireland data that shows that the roads with the highest collision rates between 2015 and 2017.
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.'
The analysis found that the most dangerous stretch of road nationwide is in Galway, located just east of Kylemore Lough, from Cliften to near Leenaune along the N59.
Earlier this month, contracts were signed for the long-awaited N81 Knockroe Bend Realignment Scheme. The works, which are expected to take 72 weeks, are intended to improve road standards by realigning and widening this section of the N81.
