Transport Infrastructure Ireland

TII is a non commercial semi-State body which operates under the aegis of the Department of Transport, Tourism & Sport. Our mission is to provide high quality transport infrastructure and services, delivering a better quality of life and supporting economic growth. TII’s primary function is to provide an integrated approach to the development, maintenance and operation of the national road network and light rail infrastructure throughout Ireland.

Specifically, in relation to national roads, our key role is to secure the provision of a safe and efficient network of national roads. In relation to light rail, the core functions of TII include securing the provision of, or to provide, such light railway and metro railway infrastructure under assignment from the National Transport Authority (NTA) as directed in the Dublin Transportation Act of 2008;
