Overview of the M5 Closure and Diversion
The M5 northbound carriageway near Exeter has been closed following a lorry fire between Junction 30 (Sandygate Interchange) and Junction 29 (Sowton Interchange). Emergency services, including Devon & Cornwall Police and Devon & Somerset Fire & Rescue, are on the scene as crews work to contain the blaze and clear the roadway. National Highways has confirmed the closure and issued a formal diversion route for road users.
The Diversion Route Explained
Drivers caught in this disruption should follow the marked diversion using local road signs with the solid diamond symbol. The route takes motorists off the M5 at J30 and re-joins the northbound carriageway later, maintaining a continuous flow away from the incident site.
Step-by-step Diversion
- Exit the M5 northbound at J30 Sandygate Interchange (Exeter A379; Exmouth A376; Sidmouth A3052; Exeter Services).
- Turn onto Sidmouth Road and proceed to the next roundabout.
- Take the second exit onto Moor Lane at the roundabout.
- Continue north on Moor Lane to the Moor Lane Roundabout with the A3015.
- Take the third exit to join the A3015 Honiton Road street-wise toward the exposed corridor.
- Turn left at the next junction to re-join the M5 northbound beyond the incident site.
Officials emphasize that the diversion is designed to keep traffic away from the fire scene while allowing essential services to operate unhindered. Motorists should observe all temporary signs and follow directions from police or traffic officers on the ground.
<h2 What to Expect for Travel Times and Alternatives
As with any significant collision, delays are likely on surrounding routes. The M5 closure disrupts one of the principal north-south corridors in Devon, particularly for freight and long-distance travel. Drivers in the area are urged to plan ahead, monitor live traffic updates, and consider alternative routes if possible to avoid peak congestion windows near Exeter.
<h2 How Emergency Services Are Handling the Situation
Devon & Cornwall Police and National Highways Traffic Officers are coordinating with the fire service to manage the incident. The lorry fire on the northbound M5 is being treated as a priority incident, with crews working to extinguish flames and secure the scene. Once the fire is under control, a risk assessment will determine when the roadway can be reopened in a controlled manner.
<h2 Practical Advice for Drivers
Keep a safe distance from the incident, follow official diversion signage, and avoid stopping on the carriageway to take pictures or assist unless directed by authorities. If you are in a vehicle impacted by the diversion, ensure your fuel, weather conditions, and travel plans are aligned with the revised route. For freight operators and long-haul travelers, consult your carrier for updated routing and expected delivery windows.
