TII's purpose is to provide sustainable transport infrastructure and services, delivering a better quality of life, supporting economic growth and respecting the environment.

TII is a state agency under the aegis of the Department of Transport, working 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 and greenways.

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, click on our information video below.
