Morning commuters across Surrey and Sussex faced a frustrating start today as major routes slowed to a crawl, with the M25 emerging as the worst affected. Drivers reported long queues, slow-moving traffic, and rising delays following multiple incidents, including collisions on the A23 and A283 that quickly rippled across nearby roads.
By mid-morning, congestion on the M25 had intensified sharply. Traffic monitoring updates showed delays reaching 24 minutes on the clockwise carriageway, with average speeds dropping to just 15 mph across key stretches. The disruption extended between junctions near Leatherhead and Chertsey, turning one of the UK’s busiest motorways into a bottleneck.
Collisions Trigger Wider Traffic Disruption
The chaos appears to have been triggered by earlier incidents on surrounding routes. A collision involving a heavy goods vehicle on the A283 near Storrington partially blocked Washington Road, creating immediate congestion between Sullington Lane and Barns Farm Lane. Traffic quickly built up between the Washington roundabout and nearby villages, with drivers forced to slow or reroute.
At the same time, another collision on the A23 near Pyecombe added further pressure to the road network. Delays were reported on the northbound approach, with traffic steadily backing up as emergency services responded. These incidents combined to disrupt key feeder routes leading toward the M25.
The ripple effect was unavoidable. As traffic diverted from affected roads, congestion spread onto surrounding highways, pushing additional pressure onto the M25 and worsening existing delays.
Roadworks and Lane Closures Add to Pressure
Ongoing construction works across the region made conditions even more difficult. On the M23 southbound exit at Junction 10 near Crawley, lane restrictions reduced traffic to a single lane, leading to heavier-than-normal congestion.
Elsewhere, drivers encountered queueing traffic on the A2270 Eastbourne Road in Willingdon, where construction activity slowed northbound movement near residential areas. Temporary traffic lights and narrowing lanes meant that even short stretches of road became choke points during peak travel hours.
Further disruption was reported on the A21 at Hurst Green, where roadworks and temporary signals caused delays on all approaches. Traffic built steadily in both directions, with vehicles moving slowly through controlled sections.
These ongoing works, combined with earlier collisions, created a perfect storm for congestion across Sussex and Surrey’s busiest corridors.
Emergency Road Closures in Surrey
Adding to the disruption, emergency repairs forced the closure of key roads in Surrey, further limiting available routes for commuters.
In Sutton, Langley Avenue was closed eastbound between Dorchester Road and the A24 London Road. Detours were put in place, but delays quickly followed as diverted traffic fed into already busy surrounding streets.
Meanwhile, in Mitcham, the A239 Cricket Green was shut eastbound for urgent repair work. Congestion stretched back along London Road and surrounding routes, with traffic building in both directions as vehicles attempted to navigate alternative paths.
These closures significantly reduced capacity across the local network, contributing to longer journey times and increased frustration among drivers.
M25 Conditions Remain the Biggest Concern
The M25 remained the focal point of today’s disruption. Traffic data showed that earlier incidents, combined with ongoing congestion, led to extended queues across multiple sections.
In one area, a stalled vehicle near Godstone forced lanes to stop temporarily, creating further delays and slowing recovery times. Congestion stretched back toward Clacket Lane Services, one of the motorway’s busiest service areas.
Traffic monitoring updates indicated that delays of 13 minutes were also recorded on other sections of the motorway, though conditions varied as congestion gradually eased in some areas.
According to live updates from AA Traffic News, the situation remained fluid throughout the morning, with delays shifting as incidents were cleared and traffic volumes changed.
Even as some areas began to improve, the combination of reduced speeds, high traffic volume, and ongoing roadworks meant that normal conditions were slow to return.
Drivers Face Slow Recovery as Traffic Gradually Eases
While some incidents were cleared later in the morning, congestion continued to linger across key routes. Queueing traffic remained on parts of the A245 near Cobham, where earlier disruptions left residual delays stretching for nearly a mile.
Across the region, the pattern was consistent: even after incidents were resolved, traffic took time to return to normal levels due to the sheer volume of vehicles on the road.
For many drivers, the experience highlighted how quickly a handful of incidents can escalate into widespread disruption across interconnected road networks.
As traffic conditions slowly improved, commuters were still advised to expect longer journey times throughout the day, particularly on routes feeding into the M25. With ongoing roadworks and peak travel demand, the morning’s disruption served as a reminder of how fragile traffic flow can be across one of the UK’s busiest transport corridors.
