Background

Main Line

The Mayo-Galway Pipeline connects the Corrib Gas Pipeline to the national gas network.[6] The project allowed for the supply of gas to new towns in Galway and Mayo for the first time. A number of new archeological sites were discovered during construction.[5]

New Towns Extension

Over a period of approximately a decade between 2004 and 2014, Gas Networks Ireland built extensions to Mayo-Galway pipeline. The extensions bring natural gas towns near the mainline route including Ballina, Ballyhaunis, Castlebar, Claremorris, Crossmolina, Knock and Westport in Co. Mayo and Athenry, Craughwell, Headford and Tuam in Co. Galway.[7] The extension to Tuam was the last pipeline to be completed and this was in 2013. [8]
