About Us
Transport Infrastructure Ireland (TII) exists to fulfil an important purpose of national strategic significance, touching the lives of citizens and visitors alike on a daily basis.
Our Remit
Light Rail & Metro
The Roads Act of 2015 expanded the remit of TII to include light railway (such as Luas) and metro railway infrastructure as may be determined by the NTA. The NTA has the statutory function of providing metro and light railway infrastructure and is the Approving Authority for public transport infrastructure and services.
National Roads
It is the general duty of TII to secure the provision of a safe and efficient network of national roads, having regard to the needs of all users. Under the Government’s Infrastructure Guidelines, TII is the approving authority for national road projects and works in partnership with local authorities, who are the road authorities for all roads, including national roads.
Greenways, Active Travel & the National Cycle Network
In September 2021, TII became the approving authority for greenways on behalf of the Department of Transport. TII is investing €60m a year in greenways up to 2030, supporting local authorities to deliver more than 200km of greenways as part of the National Cycle Network, and a further 100km of recreational greenways.
