A2 York Street Belfast closures: the September and October 2026 dates drivers need to know
A £557,000 resurfacing scheme brings four major weekend closures and weekday lane restrictions on one of Belfast's busiest approaches, with works due to run into mid-October.
Drivers using the A2 York Street corridor in Belfast face a series of significant closures through September and October 2026 as the Department for Infrastructure carries out a £557,000 road-improvement scheme.
The work covers around 800 metres of carriageway from Brougham Street to beyond Limestone Road. Because this route feeds traffic towards the M2, city centre and north Belfast, the closures are likely to matter well beyond the immediate work site.
What are the full closure dates?
DfI has published four main weekend closure windows:
- 9pm Friday 18 September to 6pm Sunday 20 September 2026
- 6am Saturday 26 September to 6pm Sunday 27 September 2026
- 9pm Friday 2 October to 6pm Sunday 4 October 2026
- 6am Saturday 10 October to 6pm Sunday 11 October 2026
The first closure is already under way this weekend, making the scheme immediately relevant to anyone travelling through Belfast.
Are there restrictions between the weekend closures?
Yes. DfI says lane closures will operate from Monday 21 September for the duration of the works. That means weekday traffic can also face slower journeys even when the road is not completely closed.
What is the diversion route?
During the full closures, the published diversion uses Brougham Street and North Queen Street. Temporary traffic signs and restrictions will be in place, and local access has been considered within the traffic-management plan.
Drivers who do not need to enter the immediate area may be better avoiding the corridor entirely rather than joining the signed diversion at the final junction.
How long will the scheme last?
Subject to favourable weather, the Department expects the works to be completed by Friday 16 October 2026. Weather-dependent roadworks can move, so anyone planning a journey later in the programme should check Trafficwatch NI or DfI updates before leaving.
Which journeys are most likely to be affected?
The York Street corridor carries traffic between central Belfast, north Belfast and the motorway network. Weekend shoppers, airport journeys using the M2 direction, event traffic and drivers heading to or from the city centre can all be affected by congestion spreading beyond the actual closure point.
The worst delays may not sit directly beside the works; queues can build on feeder roads as traffic redistributes.
How should drivers plan?
- Check whether your journey overlaps one of the four closure windows.
- Allow extra time even on weekdays because lane closures begin 21 September.
- Use live traffic information shortly before departure.
- Avoid using residential streets as improvised shortcuts where restrictions or congestion make them unsuitable.
- If catching a flight, ferry, train or timed appointment, add a larger buffer than usual.
Why PureCar is covering this closure
Routine resurfacing on a small local street is not useful motoring news for most of Northern Ireland. This scheme is different: it affects a strategic Belfast route over several weekends and includes ongoing weekday lane restrictions. That gives it a realistic chance of disrupting thousands of journeys.
DfI says it has programmed the traffic management to minimise inconvenience, but it also explicitly warns drivers to expect delays and allow additional time.
