Responsibility for the improvement and maintenance of roads in urban areas rests with individual road authorities. In the case of non-national roads, the improvement of such roads normally falls to be funded from the road authority's own resources, supplemented by the annual grants for these roads; it is generally a matter for individual road authorities to select the projects they wish to fund, subject to the guidelines which apply. In the case of national roads, any necessary improvements would be a matter for consideration by the local authority concerned and the National Roads Authority.
