 The N60 in County Mayo has seen minor realignment works carried out since the 1970s.The largest project to date is the Claremorris relief road, which was constructed in two stages between 1988 and 2000.This relief road removes the majority of the 7,000 vehicles daily from Claremorris town centre, in particular Mount Street—which was once notorious for tailbacks, as traffic previously gave way to the busy N17 that passed through the town prior to the opening of the N17 bypass in 2001.
