The
N3 road is a
national primary road in
Ireland, running between
Dublin,
Cavan and the border with
County Fermanagh. The A509 and A46 roads in
Northern Ireland form part of an overall route connecting to
Enniskillen, and northwest to the border again where the N3 reappears to serve
Ballyshannon in
County Donegal.
Rush hour congestion between Navan and Dublin city is very heavy (up to 22,000 vehicles per day on parts of the N3 in 2002), and problems occur at most built-up areas between these points. A tolled motorway bypass replacement, the M3 motorway, was opened to traffic on the 4th of June 2010. The bypassed section from
Clonee to the border with
County Cavan has been reclassified as the
R147.

Navan. Near
Kells the route continues as the N3 dual carriage way to the border with County Cavan. It then passes through
Virginia, past Cavan Town and continues past Butlersbridge and through
Belturbet. The route then crosses the border with Northern Ireland, becoming the
A509 to
Enniskillen. The A46 road connects Enniskillen and the
Donegal border, becoming the N3 across the border at
Belleek, and...
