Fatal crash on M23 near Merstham causes long delays and diversions

Surrey Police say a fatal crash occurred on the M23 near Merstham in the early hours of Sunday, involving an Audi and a VW. A man in his 50s died at the scene and his next of kin have been informed. A man in his 40s was arrested on suspicion of causing death by dangerous driving. The collision happened in a layby close to the A23 and emergency services closed the road as they worked at the scene.

Police say diversions are in place and drivers can expect lengthy delays along the route into Croydon from the M25. There is no confirmed reopening time. Investigators are appealing for witnesses to help understand how the crash happened.

The incident shows how quickly a single crash can disrupt a busy travel corridor. Beyond the immediate loss, the disruption hits commuters, local residents, and businesses who rely on the M23 and nearby roads. The arrest underscores the seriousness of the investigation and the pressure to establish what happened while keeping the public informed. Roads agencies face the challenge of balancing rapid detours with safety and clear guidance for drivers.

In the longer run, scenes like this highlight the need for resilient traffic management and transparent communication. When closures linger, a broad audience—from daily commuters to delivery drivers—feels the impact. Officials should consider how to improve real time updates and fast, safe diversion routes to reduce gridlock in future incidents.
