**Major Incident Closes A48 Junction in Cardiff Following Serious Collision**

Motorists in Cardiff are facing significant disruption after a serious road traffic incident led to the closure of a key off-slip at the busy A48 Llanedeyrn roundabout. South Wales Police have confirmed that the junction is shut and will remain inaccessible for an extended period, prompting warnings for drivers to seek alternative routes as lengthy delays build during peak travel times.

Emergency services were alerted to the scene earlier today and are actively managing the situation, though the exact details of the vehicles involved and the nature of any injuries sustained are yet to be made public. Officers have established a presence at the site to coordinate traffic management and assist with the ongoing investigation.

A spokesperson for South Wales Police issued a statement urging motorists to avoid the area where possible. “We’re at the scene of a serious collision on the A48 Llanedeyrn roundabout, Cardiff. The off-slip for this junction is currently closed. It is expected to remain closed for some time; please avoid the area and use alternative routes where possible,” the spokesperson said. “We’re grateful for your patience.”
The closure comes at a critical time, as the affected road is a major artery for commuters heading into and out of the city. Drivers are being diverted, and congestion is increasing on nearby routes, with long tailbacks reported. Public transport services operating through the area may also experience knock-on delays, so local residents and those planning to travel are encouraged to check for updates before setting out.
As rush hour approaches, the closure of the junction is expected to have a significant impact on traffic flow not only around Llanedeyrn but also across wider Cardiff. The A48 remains one of the city’s principal roads, connecting key districts and serving a high volume of daily traffic.
Authorities have not yet disclosed the cause of the crash, nor released information about those involved. Such closures often indicate the severity of the incident, particularly when additional resources are deployed to manage the aftermath and undertake thorough investigations. It is common practice for collision experts to examine the scene in detail to determine the circumstances of incidents of this nature.
South Wales Police continue to appeal for patience as they work with emergency responders to address the fallout from the crash and make the area safe. Travel advice from the force and local traffic management teams is being regularly updated online and via social media channels to keep the public informed.
Local community groups have responded with concern, sharing messages of support for anyone involved in the crash and urging fellow residents to heed police requests for route diversions. Anecdotal reports suggest that some drivers have already faced considerable delays, further reinforcing official advice to avoid the area where feasible.
For those eager to stay abreast of developments, news outlets and local authorities are offering real-time updates. Local residents are encouraged to subscribe to dedicated traffic news feeds or join online community forums, as further information is expected to be released once the initial investigation is concluded and when it is safe for the road to reopen.
This incident underlines the unpredictable nature of travel in busy urban centres and the importance of responsive communication between the authorities and city communities. As police continue their work at the scene, further updates regarding the cause of the crash and the status of the affected junction are anticipated. Meanwhile, Cardiff drivers are advised to exercise caution, plan extra time for their journeys, and monitor trusted news sources for the latest information.
