M25 Traffic Latest Update Today: Congestion
The main congestion points are:
- M25 anticlockwise: J23 to J22
- M25 anticlockwise: J22 to J21A
- Junction 23 serves the South Mimms area and connects the M25 with the A1 and A1(M).
- Junction 22 provides access towards St Albans, while Junction 21A connects the M25 with the A405 and wider road network.
Traffic queues around these junctions can affect surrounding roads as motorists enter or leave the motorway.
M25 Traffic Latest Update Today: Affected or Closed Roads
The main reported disruption remains on the M25 anticlockwise carriageway. However, nearby connecting roads could also experience heavier traffic as some motorists look for alternative routes.
The A1/A1(M) around Junction 23, the A1081 around Junction 22 and the A405 around Junction 21A are among the important routes connected to this section of the M25.
Drivers should check local traffic signs before diverting because conditions on surrounding roads can change quickly. There is currently no confirmed information in the available reports indicating a full closure of all affected sections.
M25 Traffic Latest Update Today: Diversion Routes
Drivers should follow any official diversion signs issued at the scene rather than relying on unofficial routes shared online. Motorists who do not need to use the affected section may consider avoiding the J23-J22-J21A corridor until congestion eases.
However, drivers should not automatically switch to smaller local roads, as diversions can transfer motorway congestion into nearby communities. The safest option is to check live traffic information and follow directions from National Highways and local traffic authorities.
M25 Traffic Latest Update Today: When Will Traffic Return to Normal?
There is currently no confirmed time for traffic to return to normal. The situation will depend on how quickly authorities manage the incident and how long it takes for existing queues to clear.
Even after the original incident is dealt with, congestion can continue because large volumes of vehicles may remain trapped behind the affected area. Drivers should therefore expect conditions to remain changeable and check for fresh updates before travelling.
M25 Traffic Latest Update Today: Helpline Numbers
For urgent emergencies on the motorway, motorists should contact the emergency services. For non-emergency traffic information, drivers can check official National Highways updates and live traffic services before travelling.
Motorists should avoid using a phone while driving. If they need to make a call, they should stop somewhere safe and legal first.
