Emergency Closure on London's Orbital Motorway
Drivers face significant disruption on the M25 this morning following an emergency overnight closure. National Highways East has shut a key northbound section of the motorway to carry out urgent repairs to a carriageway defect.
The traffic authority announced the closure via social media platform X late on Wednesday, December 3. The affected stretch is the M25 J21 anti-clockwise link road to the M1 J6A northbound. In addition to the link road closure, two lanes are also shut on the main M25 carriageway within J21A on the approach to the link.
Details of the Disruption and Official Advice
The works have been classed as an emergency, necessitating the immediate closure to ensure the safety of road users and to allow engineers to fix the problem. National Highways has stated this is an ongoing event and that further updates will be provided as the situation develops.
With the closure impacting a major arterial route around the capital, the authority's primary advice to motorists is clear: allow extra journey time if you need to travel through the area. The disruption is expected to cause considerable delays, particularly during the morning rush hour, as traffic seeks alternative routes.
Expected Impact and Looking Ahead
The closure of this critical interchange, where the M25 meets the M1, is likely to cause a ripple effect on surrounding road networks. Drivers heading north from London or towards the Home Counties are urged to plan their journeys carefully, check live traffic updates before setting off, and consider using alternative routes where possible.
While no estimated time for reopening has been given, the classification as emergency works suggests repairs will be conducted as swiftly as possible. Commuters and long-distance travellers alike are advised to stay informed via official National Highways channels for the latest information on this developing traffic incident.
