The Department
The Department for Infrastructure is made up of approximately 3,000 people who are industrial, professional and technical staff, engineers, planners, policy makers and administrators. DfI industrial and technical staff design, build, maintain and repair roads, bridges and street lights. They also work to ensure that flood risks are mitigated where possible and water courses are managed. Much of this effort takes place outside offices and outside office hours. Many of our teams work anti-social hours in very difficult conditions when necessary; to grit roads; to deal with the aftermath of storms, flooding and fallen trees; and to ensure the enforcement of driver and vehicle licensing laws in the interests of public safety. Under the direction and control of the Minister for Infrastructure we also develop policy options for Ministerial consideration. This includes delivering a long-term water strategy, supporting shifts to more sustainable forms of transport, increasing the efficiency of our key economic corridors and addressing the climate crisis.
