A comprehensive review of the classification of the national and regional road system was concluded in 1994 as set out in Statutory Instrument, S.I., 209 of 1994: Roads Act 1993 (Declaration of National Roads) Order, 1994 and S.I. 400 of 1994: Roads Act 1993 (Declaration of Regional Roads) Order, 1994. This review was carried out in consultation with local authorities and took account of representations received from a wide range of local interests. The update of these statutory instruments currently under way is designed to take account of road improvements and route changes since 1994. It is anticipated that the update will be concluded later this year.
