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. It has since been replaced by a new bridge.
