There are at the present time 56 miles of motorway completed and opened to traffic in Northern Ireland, a further 7 miles under construction and a further 47 miles at the project stage. These motorways are similar to those in Great Britain except for the mound barrier on the central reservation, special curbing along each side of the pavement, and a continuous 4.5 ft-wide paved strip next to the fast lane of the pavement in the central reservation. Mention is made of the predominance of boulder clay and peat and construction methods used. Details are given of aggregates and materials utilized, concrete bridge design and construction, motorway lighting systems, and preliminary survey works. Costs are quoted. /IRRD/
