The N59 road is a national secondary road in Ireland. It commences in County Sligo, south of Sligo Town at the Belladrehid interchange with the N4 north of Ballysadare. The route circles around the west of Ireland, passing west from Sligo into County Mayo and through Ballina. The N59 continues around Mayo, proceeding indirectly to Westport. Continuing south through Mayo into County Galway, the road passes through the village of Leenaun. The 182 year-old bridge in the centre of the village, carrying the road across the River Lahill, collapsed in floods on 18 July 2007. Due to the local terrain and road network, the diversionary route for getting from the south of the village to Westport was 110 km long. A temporary bridge was opened eight days after the floods, on 27 July.
