that the N5 commences on the Castlebar inner relief road at the Westport Road roundabout. However the road between Westport and Castlebar was upgraded to national primary route status in 1994 (under the Roads Act, 1993 (Declaration of National Roads) Order, 1994) and became part of the N5 road. Road signage on this route reflects this. The route no longer runs through Castlebar town centre in any case, having been bypassed by a relief road. Road signage on the N4 in Dublin was mostly patched to reflect the new destination only in the early 2000s but some signs reading Castlebar still remain elsewhere.
