Where can I check planned roadworks in Northern Ireland before starting a journey?

Use TrafficWatchNI to check current and forthcoming roadworks before travelling in Northern Ireland.

For Northern Ireland motorists, the key is to use the NI rule rather than assuming a Great Britain article says exactly the same thing. TrafficWatchNI publishes road, lane and slip-road closures, start and end dates, likely delays, diversion information and the organisation carrying out the work. It is the practical live source for DfI roadworks rather than relying on an old news story or social-media post.

For this exact issue — “Where can I check planned roadworks in Northern Ireland before starting a journey?” — check the live temporary signs first, then confirm the works entry on TrafficWatchNI if you need dates, diversion details or the organisation responsible. Temporary traffic management can alter the normal lane layout, speed limit, access or priority, so an old sat-nav route or memory of the road is not reliable evidence of what is permitted today.

Check the route shortly before departure as dates and traffic-management arrangements can change. For a long journey, also look at incidents and weather because a roadworks listing can be accurate while another event still affects the route. Where the facts of a journey or vehicle differ from the ordinary case, check the exact DfI/DVA or nidirect rule before travelling rather than extrapolating from a similar situation.

Before publishing this answer, the key factual point in “Where can I check planned roadworks in Northern Ireland before starting a journey?” was checked against current Northern Ireland official guidance. That matters because road rules, licence entitlements and enforcement details can differ from Great Britain and can change over time; the sources attached below are the ones to re-check if the rule is updated.
