Road closures and diversions in your area

Roads need to be closed occasionally for a variety of reasons, although the main reason is generally to avoid danger to the public or to those working on or adjacent to roads.

Closing a road

TransportNI manages the closure of public roads when it is necessary for road maintenance/ improvement purposes or for works by utilities (BT, NIE, Phoenix Gas and so on).  

Businesses or individuals may request a closure to allow them to carry out approved works in exceptional circumstances by making a formal application to their local TransportNI office.

At least three weeks notice is required, unless it is an emergency situation where there is an immediate danger, as there is a legal and consultative process to go through.

The design, provision, maintenance and removal of all temporary barriers, diversionary signing and the like is the sole responsibility of the applicant. Costs associated with the closure application (including any advertising costs) may also be charged to the applicant.

Emergency road closures are also possible when there is an immediate danger to the public, such as road subsidence or dangerous buildings.

For more information about road closures and diversions, contact TransportNI.

Other reasons for closing roads

TransportNI is not responsible for closing roads for certain types of events, including social or entertainment events, for filming on a road, and for most sporting events. Requests of this nature are generally dealt with by the police, with the support of the local council and TransportNI.

The following link includes information about road closures for events, such as motor sport road race events.


For routine closures, it is the responsibility of the applicant to make sure that those who will be most affected by the closure are consulted at an early stage and appropriate access arrangements put in place.


Initial consultation will typically involve the use of letter-drops to properties directly facing the road in question (frontagers), meetings/ discussions with the emergency services.

TransportNI can offer advice on the level of consultation and extent of diversionary signage needed for individual cases.

In some cases, signs giving advance notice of the closure may be required, and if the closure is expected to last for more than two weeks, TransportNI is required by law to place notices in appropriate newspapers.

The applicant is responsible for ensuring that the site is properly signed and managed.
