Details of the N5 national primary road.
Dublin, Longford -> Westport 
The N5 is 134.2 km long, commencing on the N4 Dublin-Sligo road at Longford, and proceeding west through counties Longford, Roscommon and Mayo, before terminating in Westport, County Mayo. The route connects Dublin (via the N4) to the west of Ireland.
The N5 commences in Longford town, at a junction with the N4 road. The N5 passes through Longford along Major's Well Road, New Street, Ballymahon Street (and via Dublin Street), Main Street and Richmond Street. Roughly 3 km outside Longford, having crossed the Dublin-Sligo railway line, the route follows an upgraded road, opened around 1978  and bypassing Cloondara to the northeast. This road continues across the River Shannon into County Roscommon at Termonbarry. Further west, at Cloonmore, another upgraded route section brings the N5 to Scramoge. This 8 km section, opened in 2004, was constructed parallel and to the north of the old road.
The N5 winds through Strokestown along Bridge Street and Church Street, and continues west to Tulsk. At Tulsk, the N5 crosses the N61, and continues northwest through Rathcroghan, Bellanagare, Frenchpark and Churchstreet to reach Ballaghaderreen. The road from Scramoge to Ballaghaderreen was subject to a five year pavement rehabilitation scheme between 2000 and 2005 with resurfacing of the existing carriageway, but the road has not otherwise been upgraded.
From Ballaghaderreen the route runs northwest into County Mayo. The N5 passes through Carracastle and continues west to Charlestown. Passing west through Charlestown, the N5 follows Ballagh Street, Market Square and Chapel Street. In the town centre, the N17 connects to the N5 from the north, N17-bound traffic follows the N5 back east slightly, and leaves the N5 to the south. The N5 leaves Charlestown continuing west.
Approximately 7 km west of Charlestown, the N5 follows a bypass of Swinford opened in 1993. The N26 commences along the N5 west of Swinford, and the N5 continues southwest, crossing a disused railway line after the bypass. The approx. 11 km section of N5 between the end of the Swinford bypass, through Bohola, and continuing west to Ballyvary, was upgraded to higher quality pavement from 2001 to 2004.
At Ballyvary, the N58 to Foxford commences and leaves the N5 to the north. The N5 continues as upgraded carriageway towards Castlebar, following a route section bypassing Turlough. The 7.5 km bypass and a 3 km relief road for Castlebar were built between 1988 and the early 1990s. The projects had cost IR£4.6 million out of an estimated IR£8.4 million (1989) by Nov 1990. The Castlebar Inner Relief Road skirts the south of the town, with the N60 joining the N5 from the south, and the N5 continuing southwest of the town.
The final section of N5 from Knockaphunta outside Castlebar, west to Westport, has not yet been upgraded. The N5 proceeds into Westport town itself, following Castlebar Street, Bridge Street and Shop Street (and in the opposite direction via James Street and North Mall). The N5 ends where it meets the N59 at the Octogon in Westport town centre.
Upgrades under construction and planned:
A 2.6 km single carriageway bypass of Longford to the south is planned, with the project expected to proceed to CPO in 2007.
Strokestown is to be bypassed by a 4 km standard two lane route in planning as of 2007. NRA funding of €200,000 was allocated in 2005 for a strategic corridor study for the route section between Strokestown and Ballaghaderreen. Also in planning is a project to bypass Ballaghaderreen by 14 km of standard two lane road.
In County Mayo, construction is underway as of 2007 on an 18 km single carriageway bypass of Charlestown. This will bypass the town to the south, with the new route alignment commencing at Currinah in County Roscommon, just west of Carracastle on the existing N5, which will also be bypassed. The Charlestown Bypass ends at the eastern end of the Swinford Bypass, at Cloonlara. The estimated cost of the project in 2005 was €62 million.
Route selection has been completed for a Ballyvary-Bohola bypass of 5 km, although no further progress had been made by end of 2005.
There are plans for a new ring road around Castlebar, this would include a section bypassing the existing N5. The preferred route has been identified.
A new route section of 15-17 km is in planning for the N5 between Westport and Castlebar. CPO and EIS documentation have been prepared, and the project, with an estimated cost in 2005 of €60 million, is subject to approval by the NRA.
A Northern Relief Road for Westport is also in planning, the N5 would terminate along this. The preferred route was identified, but at end 2005, a traffic survey was required for NRA approval.
