Summary

Roughan & O’Donovan provided civil and structural engineering design services for the realignment of the N26 at Cloongullane, Swinford in County Mayo. 

The proposed development aims to:

  • provide significant long-term safety benefits for all road users
  • reduce journey times
  • improve journey time reliability
  • improve access from east Mayo to the north of the county
  • promote sustainable industrial, economic and tourism development 

Solution

The proposed road development includes:

  • 1.8km of Type 2 single carriageway road
  • An 83m clear span steel composite bridge over the River Moy SAC
  • Two new culverts over tributaries of the River Moy
  • Local road realignments
  • Facilities for cyclists and pedestrians for sections of the existing N26 road and the proposed realigned road

ROD prepared the Environmental Report, the AA Screening and Natura Impact Statement (NIS) for the application to An Bord Pleanála (ABP). The scheme was approved in December 2018.

In April 2019, advanced works, including tree felling, fencing, archaeological excavations and testing and services diversions, got underway.

In October 2020, the main construction contract was awarded to BAM Civil Ltd.

Construction works began in November 2020.

Challenge

Developing a solution that minimised impacts on the qualifying interests of the River Moy SAC represented a challenge. Early engagement with the National Parks and Wildlife Service and Inland Fisheries Ireland helped identify the best solutions for the watercourse crossings. Ecological and environmental surveys and assessments were also undertaken.
