Enniskillen remains a bottleneck for long distance traffic on the Belfast <> Sligo route because all traffic must use the A4 Enniskillen Throughpass which was opened in 1986. While a big improvement over going through the town centre, this still involves going close to the heart of the busy town where strategic traffic has to mingle with local traffic and this delays both groups of users.

This scheme would see the main A4 route diverted to the south of the town. The road, as currently proposed, would be built to 2+1 standard (ie one lane each way plus an alternating overtaking lane) and extend from the A4 Dublin Road at the eastern side of the town, crossing the A509 Derrylin Road and terminating on the A4 Sligo Road at the western side of the town. The road will have to cross the Erne, and the bridge will be a significant structure.

In 2005, Fermanagh District Council issued a report making a number of claims about this road:

• "Up to 444 commercial cross-border journeys pass through Enniskillen on the average week day on their way to or from the ports of Belfast and Larne."
• "Time savings [of] 230,000-300,000 hours a year if a southern bypass was built."
• "Economic growth worth up to £2.5m a year could be prompted."

(source Belfast Telegraph, 1 April 2005)

The traffic benefits of the project are obvious. What may cause more concern is the fact that the road will run through the environmentally sensitive Erne area, close to and over some very attractive areas of shoreland.

Route Options

Roads Service released a leaflet in October 2008 which includes a map showing an "indicative line" for the new road. It's unclear whether this is the route that is actually being proposed, or if it is an early concept map. Either way, the route is shown on the map below. it would begin near the Killyhevlin Hotel on the A4 Dublin Road, immediately cross the Erne and then follow the southern shore of the Erne as far as the A509 Derrylin Road, where there would likely be a roundabout. The map then shows a futher stretch of road linking to the A4 Sligo Road outside the town. This final stretch may prove unnecessary, since the existing A509 may prove to be a sufficient route to rejoin the A4. However, Roads Service may which to choose an entirely new route in order to create a higher standard of carriageway and bypass all the urban area. It would seem likely that the existing road through the town centre would lose the "A4" label, and that this number would be reassigned to the Southern Bypass.

Updates

22 November 2009: According to this press release, Roads Service are planning to hold a public consultation event in "Autumn 2010" to reveal the general route corridor (note: not the actual route) that is being proposed for the Southern Bypass. Meanwhile, the Impartial Reporter has published an article reporting that Roads Service are exploring the possibility of introducing a one-way system in the town to ease traffic in the interim, while the Southern Bypass is being planned. (With thanks to Gary Potter).

7 June 2009: At a meeting with Fermanagh District Council two weeks ago, Roads Service confirmed that they have now appointed consultants to commence route selection work. Construction is still unlikely to commence before 2013, and perhaps not until 2018.

24 Nov 2008: Roads Service released a leaflet in October 2008 which includes a map that provides the first indications of the route that is being considered (see above). It does not give any other information on the scheme, other than to confirm that construction is anticpated between 2013 and 2018.
