A major accident on the M20 in Kent is causing significant disruption today, Wednesday, September 23, 2026, after a collision followed by a vehicle fire forced the closure of the eastbound carriageway.
The affected section is between Junction 8 at Lenham and Junction 9 for Ashford, with emergency services attending the scene and motorists facing substantial delays.
National Highways said the closure is expected to remain in place for several hours while the incident is dealt with and the circumstances are investigated.
What Happened on the M20 Today?
The crash was reported on the eastbound M20 between Junctions 8 and 9 during the Wednesday morning period.
National Highways described the incident as a collision and car fire.
Kent Fire and Rescue Service sent three fire engines and a technical rescue unit to the scene.
The scale of the emergency response has resulted in the complete closure of the affected eastbound section while crews work at the location.
M20 Eastbound Closed Between J8 and J9
The motorway is currently closed eastbound between Junction 8, Lenham, and Junction 9, Ashford.
The closure is creating delays for motorists travelling toward Ashford, the Channel Tunnel and Dover.
National Highways reported approximately three miles of congestion, with journey times already affected.
The closure is expected to remain in place for a number of hours as emergency services and investigators deal with the aftermath of the crash.
M20 Diversion Route
Motorists travelling eastbound are being directed to leave the M20 at Junction 8 and use the A20.
Drivers can then follow the signed diversion toward Ashford and rejoin the M20 at Junction 9.
Freight traffic travelling toward Dover is being advised to consider the A2/M2 instead.
Drivers should follow official diversion signs and avoid attempting to enter the closed section.
Traffic Delays Build Across Kent
The collision has created substantial congestion during the morning travel period.
With several miles of queuing reported, motorists using the M20 should allow considerably more time for their journeys.
The impact could also extend to nearby roads as traffic diverts away from the closed motorway.
Drivers should check the latest traffic conditions before travelling through the area.
Emergency Crews Remain at the Scene
Kent Fire and Rescue Service deployed multiple fire appliances and a specialist technical rescue unit following the crash.
Police and National Highways personnel are also involved in managing the incident and securing the motorway.
The emergency response is expected to continue while the scene is made safe and investigators establish what happened.
Injuries and Fatalities Not Yet Confirmed
At the latest update, the available reports did not provide a confirmed number of people injured in the collision.
There is also no confirmed fatality reported in the information currently available.
The circumstances of the crash, including the number of vehicles involved and the cause of the collision, remain under investigation.
Unconfirmed reports about deaths or serious injuries should therefore not be treated as established facts.
