The N7 is the main road from Dublin to Limerick. All but 20 km of it have been upgraded to motorway.

Route

The N7 Naas Dual Carriageway

Today's N7 begins at the Red Cow Interchange (locally nicknamed the "Mad Cow" interchange) with the M50. It heads southwest down Naas Road as a high speed dual carriageway. While there are some LILO junctions and access to private businesses, all crossover junctions have been removed. The last and most notorious of these was a set of traffic lights at Newlands Cross with the R113, this bottleneck was finally replaced by a grade-separated junction on 20 November 2014.

Some 12 km from the M50 the route crosses into County Kildare just west of J5 and after a further 8 km it becomes the M7 at J9.

History

The original start of the N7 was on the N4 in Dublin by the National War Memorial Garden. Roads inside the M50 were generally downgraded to regional status when that motorway opened. It followed what's now the R110 to Red Cow. The bypassed sections of N7 by the M7 are now mostly the R445. It ended in the centre of Limerick by Mathew Bridge.

The N7 Naas Dual Carriageway was built as a D2 all purpose road in the 1960s - it was the first significant section of dual carriageway in the Republic of Ireland, and was completed (22 km from Bluebell in Dublin to Naas) in March 1968. It was a very dangerous road when it first opened as Irish drivers had no experience in using a dual carriageway - fatal accidents were very common in its early years. In the 1970s traffic lights were installed at some major junctions and around 1972 a short section from the Longmile Road junction to Newlands Cross was widened to D3AP.

The Naas bypass was, in 1983, the first motorway to open in the Republic of Ireland.

The Naas Dual Carriageway was widened from D2AP to D3HQDC in two phases in 1998 and 2006 - the latter in time for the Ryder Cup Golf tournament at the K Club golf resort. It remains an all-purpose road owing to the lack of an alternative route for non-motorway traffic.
