As Minister for Transport, Tourism and Sport, I have responsibility for overall policy and funding in relation to the national roads programme. Under the Roads Acts 1993-2015, the planning, design and operation 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 the question to TII for a direct reply to you in respect of improvement measures for the M50. Please advise my private office if you do not receive a reply within 10 working days.
