National primary routes were informally designated in 1969 and formally declared in June 1977 under the Local Government (Roads and Motorways) Act, 1974, (Declaration of National Roads) Order 1977. There was no traffic census in 1970 and data are instead provided for 1968, the year prior to the informal designation. Data are also provided for 1980. Since 1980, there has been no full census of traffic on national routes. A new traffic counting system is at present being installed with a view to carrying out a census during 1985.
The following table sets out the figures for 1968 and 1980:—
