Traffic disruptions persist on the M4 in Wales due to emergency repairs and multiple incidents.

Topics covered
UPDATE: Significant delays are affecting several sections of the M4 motorway in Wales, particularly around the Prince of Wales Bridge. Emergency repairs are underway on the eastbound lanes, specifically from junction 23 (M48) to junction 22 (M49). These repairs are causing extensive traffic backups, significantly impacting daily commuters and travelers in the region.
Current Traffic Situation
The situation on the M4 has worsened due to additional incidents. A broken-down vehicle on the westbound carriageway at the Cardiff West exit has led to further delays. Furthermore, a crash between junction 42 (Swansea East/Briton Ferry) and junction 43 (Llandarcy) has resulted in traffic being slowed by approximately 30 minutes.
Traffic service Inrix reports that conditions are very slow in these areas.
As of now, the westbound exit slip road at junction 33 A4232 (Cardiff and west services) has reopened after being closed due to the broken-down vehicle. Reports indicate that traffic in this specific area appears to have returned to normal.
However, emergency repairs on the Prince of Wales Bridge continue to affect two lanes, resulting in long delays.
Details of Incidents and Road Conditions
According to eyewitness accounts and traffic reports, the delays on the M4 are not limited to the bridge repairs. Ongoing issues from the broken-down vehicle and the recent crash have created a perfect storm of traffic congestion. This combination has made travel particularly challenging for those navigating the busy roadway.
Authorities are actively managing the situation and providing regular updates. Motorists seeking to travel in the area are advised to remain informed of the latest developments and consider alternative routes when possible.
Official Statements and Recommendations
Local traffic management authorities urge drivers to exercise patience and caution while traveling through the affected areas. “We are working diligently to resolve these issues as quickly as possible, but we anticipate delays will continue as repairs are underway,” stated a spokesperson. The advice remains clear: avoid the M4 if you can, and stay tuned for further updates.
As the situation evolves, we will provide real-time updates to keep travelers informed. Please remain vigilant and prepared for potential delays if you plan to use the M4 in the near future.
