Lanes closed after blaze on busy Gatwick approach
Traffic reports indicate a vehicle became engulfed in flames on the M23 southbound on 25 August 2026, affecting drivers travelling towards Gatwick Airport. The incident was reported between junction 8, where the motorway meets the M25, and junction 9 for Gatwick Airport, one of the busiest stretches of road serving the airport.
Images shared on social media and carried by news outlets show a van on the southbound carriageway completely alight, with thick black smoke rising above the motorway. The vehicle came to a halt in a live lane, prompting an immediate response from emergency services and triggering an urgent closure of part of the carriageway as firefighters tackled the blaze.
National Highways updates cited by local media indicated that two of the four southbound lanes were initially closed while crews dealt with the fire. The closures were later gradually reduced as the vehicle was extinguished and made safe, but residual restrictions remained in place while debris was cleared and the carriageway was inspected.
Surrey Fire and Rescue Service was reported to be at the scene managing the incident, with motorists advised to pass the location with caution and to expect ongoing disruption as traffic slowly filtered through the remaining open lanes.
Long delays and four miles of congestion reported
The lane closures quickly translated into heavy congestion on the M23, with queues building back several miles towards the M25 interchange. Travel reports described around four miles of slow-moving traffic on the approach to junction 9, adding upwards of 30 minutes to journey times for affected drivers.
Vehicles heading for Gatwick Airport, as well as those continuing further south towards Crawley and the A23 corridor, were caught in the disruption. Motorists reported extended stop-start conditions, with some describing traffic at a near standstill in the build-up to the incident.
National Highways traffic feeds referenced in news coverage advised drivers to allow extra time for their journeys or consider alternative routes where possible. Those using the M25 and planning to head south towards Gatwick were encouraged to monitor live traffic updates before committing to the route, as the knock-on effect of the closure continued for some time after the fire was brought under control.
The delays were felt most acutely during the late morning travel period, when both airport traffic and commuter flows are typically heavy. Even after all lanes had reportedly reopened, residual queues remained as congestion slowly eased along the southbound carriageway.
Impact for Gatwick passengers and local motorists
The M23 is the primary motorway link for Gatwick Airport, funnelling a high proportion of passengers, staff and service vehicles between the hub and the wider motorway network. Published transport assessments for the airport note that the section between junctions 8 and 10, along with the spur to the terminals, carries a large share of airport-related traffic, particularly at peak times.
As a result, even short-lived incidents on this stretch of road can have an outsized effect on access to the airport. Tuesday’s van fire came amid already busy late summer travel, and reports suggested drivers heading to flights or returning from trips faced the risk of delays reaching the terminals while the incident was ongoing.
Publicly available information did not indicate any direct impact on flights, and Gatwick’s runways and terminal operations continued as normal. However, motorists making airport runs were advised to factor in additional travel time and to check conditions on the M23 before setting off, especially from the London and M25 side.
For local drivers using the M23 for journeys between Surrey and West Sussex, the disruption added to a period of heightened attention on key routes around Gatwick following recent rail and road issues in the wider area earlier in August. The incident reinforced how quickly congestion can build when even partial closures occur on this busy strategic corridor.
Motorway fully reopened but residual delays linger
Once firefighters had extinguished the blaze and confirmed the vehicle was safe, attention turned to making the carriageway fully operational again. Traffic monitoring services reported that all lanes were eventually reopened after debris was removed and any necessary safety checks completed.
Despite the full reopening, queues took time to clear due to the volume of traffic already in the area and the compressed flow caused by the earlier lane closures. Drivers continued to face slower speeds and intermittent delays as traffic thinned out towards midday.
Recent official documents on the M23 and Gatwick access routes highlight that, despite capacity improvements in recent years, the corridor remains sensitive to incidents such as breakdowns and collisions, which can rapidly trigger long delays. The van fire illustrated how a single vehicle problem can significantly affect motorway conditions when it occurs close to a major airport junction.
Motorists are routinely advised to monitor live traffic services when travelling to major airports such as Gatwick, particularly when journeys rely on a small number of strategic links like the M23. Tuesday’s disruption served as a reminder of the importance of allowing contingency time on days when roads are expected to be especially busy.
Travel advice for upcoming journeys via the M23
With the southbound carriageway now reported to be running normally again, drivers planning trips to Gatwick Airport in the coming days are expected to find the route clear of incident-related restrictions. However, transport guidance consistently stresses the value of checking for fresh updates before setting off, as conditions on the motorway network can change quickly.
Travellers heading to the airport by car are encouraged to build additional time into their journeys in case of renewed congestion on the M23 or connecting roads, particularly during morning and evening peaks. Where possible, those with flexible plans may wish to avoid the busiest departure windows to reduce the risk of missing check in or security slots as a result of traffic delays.
Alternative access options, such as rail links from London and the south coast, remain an important part of Gatwick’s surface transport mix and can offer resilience when road incidents occur. Nonetheless, for many passengers and staff who rely on the motorway, the van fire highlighted how essential a smoothly operating M23 is to keeping journeys to and from the airport on track.
For now, the focus for drivers is on normal traffic flow returning along the corridor, with only the memory of Tuesday’s dramatic blaze and the queues it caused lingering for those who found themselves caught up in the disruption.
