Information About

N4 Road





N4 PRIMARY ROAD

The N4 road is a National Primary Route in the Republic Of Ireland , running from Dublin to the northwest of Ireland and Sligo Town . The N6 Road to Galway diverges from this route after Kinnegad , while the N5 Road to Castlebar and Westport diverges at Longford Town .

Road Standard

The road is a dual carriageway from Heuston Station , Dublin to Mullingar (including the motorway section). This section of road intersects with the M50 Motorway at Junction 7. The Liffey Valley Shopping Centre is located at this junction. It has three lanes and a bus lane in each direction between the M50 and east of Lucan. However the speed limit was for many years after its upgrade (in 1999) only 60 km/h (previously 40 mph) on this strech, despite the quality of the road. In June 2005 , the speed limit was increased to 80 km/h. The road becomes a dual carriageway again through Sligo Town .
