ANNAGHLOY BRIDGE
The road bridge providing access to Annaghloy Peninsula/Point had continued to deteriorate in recent years and has been replaced with a reinforced concrete matiere culvert. The structure spans a circa 100m long by 2.5m wide channel in Lough Arrow that links Lough Brick Bay and Canal Bay saving a circa 5km boat trip. The clearance for boat users at the original structure had always been of concern and was only in the order of 0.6m, (water level to bridge soffit). The bridge provides the only land access to the five inhabited dwellings and six farm holdings on the peninsula.
The totally inadequate headroom, combined with the poor bridge condition and poor road alignment at the bridge, left little choice but to replace the structure with a larger more suitable structure, where the road surface can be raised sufficiently to pass over the new bridge clearance requirements and provide tolerable stopping sight distance.
The existing road level was increased by 1m to accommodate the increase in structure height. The new bridge provides an increase in height of 750mm and in width by 2m to facilitate boat users in this area. During construction of the new bridge a temporary route was provided across the channel. Poor ground conditions and rising water levels made this work very difficult. The work included the excavation and placing of a reinforced concrete base for the precast culvert, placing of the culvert, building of masonry stone spandrels walls on each side of the culvert and the surfacing of the carriageway. The project was funded by a Special Improvement Grant from the Department in 2006.
RAGHLY HARBOUR IMPROVEMENT
During 2005 a new slipway was constructed in Raghly Harbour as the first phase of a major improvement scheme. The project was conceived with the community group and promoted in partnership with the Community and Enterprise Directorate during 2003 and 2004 who secured Phase II funding for the slipway and other ancillary works. The Infrastructure Directorate took on the management of the contract to build the slipway which was completed in September 2006.
The Department of Communications, Marine and Natural Resources provided funding for the much larger Phase II project involving a new quay, new jetties, extensive dredging and ancillary works. The 2006 allocation budget was €0.845m – Love Contracts was awarded the contract which has a number of difficult aspects that are being overcome. Additional funding has been sought from the Department of Communication Marine and Natural Resources to complete the project fully. The contract should be completed by the summer of 2007.
COASTAL PROTECTION 2006
For a number of years Sligo County Council applied to the Department of Communications, Marine and Natural Resources for funding to repair/reconstruct the Ardnaglass River outfall structure at Dunmoran Strand. In late August 2006, notification of finance arrived and a programme was immediately put in place to carry out the project. A bathymetric survey was carried out followed by numerical analysis to establish wave heights at the outfall site. This provided information for the design of the replacement structure. Subsequently tender documents were prepared, Part 8 planning permission was obtained and a contract was let following an open tender process to Ascon Ltd in November 2006.
The works comprise:
- New portion of Eastern structure
- Reconstruction of Western structure
- Reconstruction of masonry training wall along river bank
- Some rock armour terminal protection
- A footbridge and associated footpath
The project is due for completion by late spring 2007 and is managed by the Marine and Structure Section in the Infrastructure Directorate.
