M25 Traffic Live: Severe Summer Getaway Delays At Dartford Crossing And Junction 10 Wisley Today
Millions of drivers face severe delays on the London Orbital Motorway today, Saturday, August 8, 2026, as peak summer holiday traffic collides with planned maintenance and emergency roadworks. National Highways has issued amber travel alerts for several key sectors of the motorway, with travel times currently extended by up to 60 minutes. Commuters and holidaymakers heading toward major airports and coastal ports are advised to check live routing data before departing.
| Hotspot / Junction | Current Delay | Cause of Disruption | Recommended Alternative |
|---|---|---|---|
| J10 (Wisley / A3) | 45 mins | Ongoing J10 improvement works & lane closures | A3 / A245 diversion |
| Dartford Crossing (A282) | 60 mins | Heavy summer getaway volume & vehicle breakdown | Blackwall Tunnel (height restrictions apply) |
| J14 to J16 (Heathrow/M40) | 30 mins | Heavy holiday traffic flow | Local routes via A3112 / A412 |
| J25 to J27 (M11 link) | 20 mins | Speed restrictions & minor accident | A10 to A414 |
Context & Background
The gridlock experienced today, August 8, 2026, stems from a combination of peak seasonal getaway travel and critical infrastructure upgrades. As August is prime holiday season in the UK, traffic volumes have surged on routes leading to Heathrow Airport, Gatwick Airport, and the southern ferry ports.
The most significant bottleneck remains at Junction 10 (Wisley), where the ongoing National Highways improvement scheme has restricted lane capacities. While this massive multi-year project aims to dramatically improve long-term safety and flow on the M25 and A3, its current construction phase is causing severe friction during high-demand weekends. Additionally, a broken-down heavy goods vehicle (HGV) near the Dartford Crossing northern tunnel earlier this morning triggered immediate tailbacks stretching past Junction 3.
Impact & Utility
The ongoing disruptions are impacting both commercial logistics and leisure travelers. To minimize time lost in traffic, drivers are urged to adopt strategic travel planning and leverage real-time mapping tools.
- Check Live Feeds Frequently: Rely on smart navigation apps that update dynamically to bypass sudden bottlenecks as they develop.
- Pre-Pay the Dart Charge: Ensure your Dart Charge account is funded in advance of reaching the crossing to prevent administrative delays and potential fines.
- Perform Vehicle Inspections: High summer temperatures increase the risk of overheating and tyre blowouts. Inspect tyre pressure, engine coolant, and oil levels before starting your journey.
- Time Your Departure: If possible, delay travel until after 6:00 PM when the initial wave of holiday and day-tripper traffic begins to subside.

What's Next
National Highways expects high traffic volumes to persist on the M25 throughout the remainder of the afternoon, with peak congestion projected to last until at least 5:00 PM today. Recovery teams are actively working to clear minor incidents on the shoulder near Heathrow to restore normal lane flow.
Looking ahead to tomorrow, Sunday, August 9, 2026, a secondary wave of return traffic is anticipated. Drivers should prepare for slow-moving queues starting from midday Sunday, particularly on the clockwise stretch approaching the Dartford Crossing and the anticlockwise lanes nearing Surrey.
