Motorists on the M25 anticlockwise faced significant delays on Friday evening, February 28, 2025, due to a medical emergency leading to the closure of the entry slip road at Junction 27 (Stansted) from the M11 North.
The incident was first reported at 17:23, and all lanes on the affected slip road had to be closed to facilitate emergency services. This traffic disruption was compounded by earlier congestion caused by a broken down vehicle, leaving many drivers stranded and frustrated.
According to National Highways, normal traffic conditions were not expected to resume until between 20:30 and 20:45. Motorists planning to use this route were strongly advised to seek alternative travel options and allow for extra time due to the extensive delays.
The region surrounding the incident, particularly near Theydon Bois, was significantly affected, located approximately 1.23 miles away from the motorway closure. Authorities urged road users to stay informed through live traffic updates and follow guidance for detours.
Traffic data monitoring company, Inrix, remarked on the severity of the situation, indicating, "Severe delays due to earlier medical incident on M25 anticlockwise from J27 (M11 interchange) to J26 A121 Honey Lane (Waltham Abbey)." They noted the challenges faced by both motorists and highway officials as clearing efforts unfolded.
A spokesperson for National Highways reported, "This incident is now clear, and the #M25 in #Essex is now OPEN anti-clockwise between J27 (#M11) and J26 (#WalthamAbbey). There's a 30 minute residual delay and 3 miles of congestion. Thanks for your patience this evening." This statement reflected the reopening of the road around 18:00, following about one hour of closure.
Despite the reopening, traffic officials cautioned drivers about residual congestion, with long queues remaining on the M25 for around another hour after the road was cleared. This indicates the knock-on effects of road incidents can linger, even after official clearance.
Another spokesperson from National Highways acknowledged the frustration among motorists caught up during the incident, stating, “Traffic caught within the closure of the #M25 anti-clockwise between J27 (#M11) and J26 (#WalthamAbbey) is now being released. The closure at J27 will be removed shortly.”
The overall message from the authorities was one of gratitude for public patience during the ordeal, highlighting the efficiency of the emergency response teams and the processes put in place by traffic management services.
For drivers previously planning to traverse this heavily trafficked route, it served as a reminder of the unpredictability of road conditions. This incident underlines the importance of checking real-time traffic information, especially during peak hours.
Motorists are reminded to remain alert when on the road and to stay informed through official traffic channels for the latest updates. With medical emergencies and vehicle breakdowns posing risks to smooth traffic flow, preparedness and awareness are key for all road users.
Officials continue to recommend diversions when necessary, advising commuters to take alternate routes to avoid potential delays on the M25 during similar future incidents. The ramifications of such emergencies reinforce the need for everyday road safety and diligence when traveling.
Moving forward, the M25 remains one of the busiest motorways, and as is always the case, preparations for similar unexpected events are prudent for both drivers and traffic authorities alike.
