A 23-year-old woman has died and a man has been left with life-altering injuries following a high-impact, single-vehicle collision on the M23 northbound near Gatwick Airport. The incident, which occurred in the early hours of Thursday, 2 April 2026, has triggered a massive police investigation and a total closure of the northbound carriageway, causing severe disruption to airport transit and regional logistics. For travelers and commuters, this event marks a critical failure in road safety on a primary artery, resulting in forensic recovery operations that are expected to last well into the evening. This is reported by The WP Times, citing trafficengland.

Forensic Investigation and Criminal Charges

Sussex Police confirmed that a 23-year-old female passenger was pronounced dead at the scene by paramedics, while a second passenger, also aged 23, remains in critical condition at a local trauma center. The driver, a 21-year-old male from London, was taken into custody at the scene; he faces grave legal repercussions, having been arrested on suspicion of causing death by dangerous driving and causing serious injury by dangerous driving.

According to the Road Traffic Act, these charges carry significant custodial sentences, and the police are currently appealing for dashcam footage from any vehicles in the vicinity at the time of the impact.

Traffic Diversions and Practical Advice for Travelers

National Highways has implemented an emergency diversion protocol to mitigate the gridlock affecting passengers heading to Gatwick Airport. Motorists are strictly advised to exit the M23 at Junction 10 and follow the A264 eastbound toward Felbridge, then proceed via the A22 and A264 toward the M23 Junction 6 (Godstone). Travelers with scheduled flights from Gatwick are urged to allow at least two hours of additional travel time or utilize the Gatwick Express rail service, which remains unaffected by the motorway closure.

Police have warned that the northbound section will only be reopened once the "Scena Criminis" has been fully processed and the wreckage recovered, emphasizing that safety and evidence preservation remain the operational priorities.

To navigate this disruption effectively, commuters should consider the following:

  1. Monitor Live Feeds: Use official apps from National Highways or Sussex Police for real-time updates on lane openings.
  2. Verify Flight Status: Contact airlines directly as staff and crew may also be delayed by the M23 closure.
  3. Alternative Routes: Avoid the A23 through Crawley as it is currently experiencing "overflow" congestion from diverted traffic.
  4. Evidence Contribution: If you witnessed the vehicle leaving the road, contact Sussex Police via 101 quoting "Operation Telemetry."
