At the outset, I should explain that overall responsibility for the planning, design and implementation of national road improvement projects, including the Dublin Port Tunnel, is a matter for the National Roads Authority (NRA) and the local authorities concerned. I have no function in relation to the day-to-day operation of these projects.

As with all major infrastructure projects Cost Benefit Analysis was carried out by the NRA in line with Department of Finance investment appraisal guidelines. In light of traffic growth in the Dublin area in recent years there are no indications that the conclusions of that Cost Benefit Analysis have significantly altered. In line with Department of Finance guidelines, a post-completion Cost Benefit Analysis will be carried out in due course.
