Advice for drivers
- Check traffic updates before setting out — the A23 is one of the main routes between Croydon and central London, so closures can cause significant delays on surrounding streets.
- Follow signed diversions and allow extra time for journeys through Thornton Heath.
- If you were near Colliers Water Lane just before 7am and saw what happened, or have dashcam footage, police will want to hear from you. As with other serious collisions in the capital, including a fatal crash in Enfield, witness accounts can prove vital in establishing what happened.
Drivers are urged to find alternative routes while the investigation continues, and bus services through the area may also face disruption. Commuters heading into Croydon town centre or towards Streatham should allow extra time and check live travel updates before leaving. The road is expected to reopen once police have completed their work at the scene, though no timeframe has been given.
Enquiries into the circumstances of the crash are continuing. No further details have been released at this stage. London Streets will update this story as more information emerges.
