With regard to the issue of national roads, as Minister for Transport, Tourism & Sport, I have responsibility for overall policy and funding in relation the National Roads Programme. Under the Roads Acts 1993-2015, the planning, design, construction and upgrading of individual national roads is a matter for Transport Infrastructure Ireland (TII), in conjunction with the local authorities concerned.
Noting the above position, I have referred your question concerning national roads to TII for a more detailed and direct reply. Please advise my private office if you do not receive a reply within 10 working days.
I can also advise that, implementation of the Regional and Local road improvement projects (including traffic monitoring) is the responsibility of the relevant road authority.
