Completed works (looking north).
Roughan & O'Donovan (ROD) is delighted that the N56 Letterilly to Kilraine Road Scheme - Phase 1 in Donegal has been shortlisted for International Project of the Year at the Ground Engineering Awards 2023.
ROD was engaged by Donegal County Council to provide construction and handover stage consulting engineering services for this road development scheme located just north of Glenties.
The scheme comprises:
- 4.1km of Type 3 single carriageway
- 2.5m wide cycletrack
- 0.6km of pavement overlay
- realignment of five local side roads and direct accesses
- a new arch bridge structure
- reinforced soil wing walls
- part demolition of Sruhangarve Bridge
Construction began in early 2021, with Wills Bros Ltd. as the main contractor, and was largely completed by November 2022.
Innovative geotechnical construction solutions, including the staged construction of large embankments on very soft peat soils, were implemented on the project to mitigate the risk to sensitive environmental receptors.
