Transport Infrastructure Ireland's role as a state agency is to provide sustainable transport infrastructure and services, deliver a better quality of life, support economic growth, and respect the environment.
Under the aegis of the Department of Transport, we work at both national and regional level, in partnership with Local Authorities regarding national roads and greenways, and the National Transport Authority (NTA) regarding light rail and metro.
TII was established through a merger of the National Roads Authority (NRA) and the Railway Procurement Agency (RPA) under the Roads Act 2015, and was set up to deliver and operate safe and efficient light rail and national road networks.
In 2021, TII was delegated additional functions in relation to active travel. We are leading the development of an ambitions new National Cycle Network for Ireland on behalf of the Department of Transport.
At TII we are building a more sustainable economy and a better quality of life for everyone. To learn more about our organisation and the valuable work that we do to keep people and goods moving safely and reliably every day, visit us at tii.ie.
