Stretch had no safe overtaking for 90% of length
The N4 Collooney to Castlebaldwin Road Project is 15km long and will connect to the previously upgraded sections of the N4 corridor and significantly contribute to the provision of a consistent quality national road link between Dublin and the North West Region.
This project is part of the Project Ireland 2040 and the National Development Plan (NDP) 2018-2027.
According to the Department of Transport, the existing stretch of road has no opportunity for safe overtaking for 90% of its length.
It has a very high accident rate with nine fatal, 10 serious and 81 minor accidents over the period from 1996 to the end of 2018.
The N4 route between Collooney and Castlebaldwin currently brings all traffic through a badly aligned narrow single carriageway road with a large number of minor junctions as follows:
· 24 junctions with local roads
· 4 crossroad junctions
· 78 houses with direct access onto the N4
· 152 agricultural accesses with direct access onto the N4
The N4 National Primary Route from Dublin to Sligo has been identified as a strategic radial corridor, which should provide a high quality link between Dublin and Sligo.
The N4 Collooney to Castlebaldwin Road Project will provide 13.8km of Dual Carriageway (Type 2), and 0.9km of Single Carriageway, from the existing N4/N17 Toberbride roundabout at Collooney, to Cloghoge Lower Td, south of Castlebaldwin Village.
