Road Closure: A40 — St Clears East

The A40 eastbound carriageway at St Clears East will be closed to traffic from 29 July 2026 at 20:00 to 10 August 2026 at 06:00 due to roadworks. The Welsh Government, the highway authority responsible for the maintenance of this stretch of road, has announced that diversions will be in place during this period to minimize disruptions to motorists. The closure, which is scheduled to last for nearly two weeks, will undoubtedly cause some inconvenience to drivers who regularly use this route, especially those commuting to and from St Clears East.

The roadworks, which are part of a larger effort to improve the road network in the area, will involve significant construction activities that cannot be safely carried out while the road is open to traffic. As a result, drivers will need to plan alternative routes to avoid the closure. The Welsh Government is advising motorists to check traffic apps and websites for the latest information on traffic conditions and to plan their journeys accordingly. By doing so, drivers can reduce their travel time and avoid getting stuck in traffic congestion.

It is worth noting that the closure will only be in place during the nighttime hours, from 20:00 to 06:00, which should help to minimize the impact on daytime traffic. However, drivers who need to travel during these hours should still expect significant delays and should plan their journeys well in advance. The Welsh Government is working to complete the roadworks as quickly as possible, but the safety of motorists and construction workers is the top priority, and the closure is necessary to ensure that the work can be carried out safely.

Drivers who are affected by the closure can use alternative routes, such as the A477 or the A48, to avoid the roadworks. However, these routes may also be busy, especially during peak travel times, so it is essential to check traffic conditions before embarking on a journey. The Welsh Government is also advising motorists to allow extra time for their journeys and to follow the diversion signs that will be in place to guide them around the closure.
