N59 Letterfrack West

  • Client: Galway County Council
  • Location: Letterfrack, Co. Galway

About this Project

The N59 Letterfrack West 2019 project consisted of realignment of the N59 just outside Letterfrack village at the entrance to the Connemara National Parks. 

The Project includes earthworks with over 15,000 m3 of rock to break out with a finished rock face height of over 10m.  


50ton excavators with breakers were used to break out the rock with 20 & 30ton excavators used to dig and load the rock onto lorries for removal off site, this work was logistically complicated as the site was very small and restricted with the site being in an environmentally sensitive location.

 Extensive silt traps and other mitigation measures were installed to prevent any damage to the surrounding SAC areas.

Works were completed in and around Connemara National Park which is a Special Area of Conservation (SAC)

Works were carried out on the N59 with a speed limit of 100km/h and an AADT > 3,000. Traffic Management was designed, implemented and monitored throughout the works by P&D Lydon.
