National Roads Authority

The National Roads Authority's (NRA) primary function, under the Roads Act 1993, was to secure the provision of a safe and efficient network of National roads. They were responsible for the planning and supervision of construction and maintenance, publishing the NRA DMRB and NRA MCDRW. In 2016 the NRA merged with the Railway Procurement Agency (RPA) to form a new organisation, Transport Infrastructure Ireland (TII).
