The N55 Corduff to South of Killydoon Realignment Scheme, Section A seeks to improve a 3.2km section of the N55 south of Ballinagh Co. Cavan.
The road realignments of Section A are located at two discrete locations approximately 1.8km apart at the following locations:
Phase 1: Approximately 1.2km long realignment section of the N55 south of Ballinagh between the townlands of Garrymore and Pottahee, and
Phase 2: Approximately 2km long realignment section of the N55 south of Ballinagh in the townlands of Ballytrust, Oghill and Corduff (to tie in with the previous 2012 N55 Corduff realignment).
Improvements to the N55 are supported in a number of the key policy documents including the Cavan County Development Plan and the National Secondary Road Needs Study 2011.
The condition of the sections of the N55 between Pottahee and Garrymore (Phase 1) and between Corduff and Ballytrust (Phase 2) is a legacy route corridor which fits within the existing landscape without consideration of modern road design requirements. As a consequence the alignment is below current standards, is narrow and bendy and particular road safety concerns are associated with narrow sections with weak edges, no grass margin and very steep side slopes. A need was therefore identified to improve the condition of the N55 in the area for route consistency between existing route improvements in the area.

Nature and extent of the proposed development
Principal aspects of the construction scheme will include provision of approximately 3.2km of new Type 2 single carriageway, typically with 7m wide single carriageway road, with 0.5m wide hard strip and 3m wide verges on both sides, the re-alignment of approximately 310m of local roads and the provision of a new roundabout on the southern outskirts of Ballinagh.
Both Phases 1 & 2 involve online realignment and new alignment construction, with Phase 1 predominantly in cutting while Phase 2 is predominantly in fill. Both Phases require significant excavation of soft soils beneath embankments.
Associated works for both Phases include; side roads, traffic management, boundary fencing and walls, safety barriers, carriageway drainage, attenuation ponds, road pavements, traffic signs and road markings, road lighting and service diversions.
The Proposed Development has been designed, based on standards set down in the National Roads Authority Design Manual for Roads and Bridges (NRA DMRB).
Environmental studies have been carried out to ensure that all environmental considerations and impacts are taken into account. Various issues, such as Noise, Visual, Landscape, Archaeology, Water Quality, Flora and Fauna etc have been assessed. (The findings of these studies are detailed in documents 'EIA Screening Report - N55 Corduff to South of Killydoon' March 2014 and 'AA Screening Phases 1 and 2 - N55 Corduff to South of Killydoon' March 2014)
Planning Permission (under Part 8 of the Planning and Development Regulations, 2001 to 2012) for the construction of the scheme was approved and passed by Cavan County Council Elected Members at the June 2014 Council Meeting.
The Compulsory Purchase Order (CPO) for the Scheme was confirmed by Cavan County Council in May 2015 following confirmation from An Bord Pleanála that no objections to the CPO had been received. This was testament to the ongoing cooperation and assistance of the landowners affected by the scheme.
The contract to construct the N55 Corduff to South of Killydoon Realignment Scheme, Section A has been awarded to Fox Building and Engineering Ltd. The Main Construction Contract works commenced on site in June 2017 and the scheme is due to be completed in October 2018.
Cavan County Council requests the patience of road users during the construction works and urges motorists to show due care and attention for the reduced speed limits that will be in place for the duration of the works.
