Marsh Mills (Cardiff Daily) January 26, 2026 – Emergency services are managing a major car fire on the A38 near Marsh Mills roundabout, which has closed the exit slip road and triggered extensive tailbacks during the morning rush hour. According to traffic and travel website Inrix, the closure is impacting one of the main routes into Plymouth city centre from the A38, forcing motorists onto alternative paths. This has resulted in congestion not only on the A38 but also along subsidiary roads such as the Dark Lane turn-off and through much of Plympton.​

What Caused the A38 Car Fire Near Marsh Mills?

Images captured by passengers in passing cars depict a white vehicle positioned at the side of the road with its engine fully ablaze, suggesting a sudden mechanical failure or fuel-related ignition. As reported in social media updates from local drivers shared via platforms like Facebook, the blaze produced significant smoke plumes visible from afar. No official cause has been confirmed by authorities at this stage, though fire service protocols indicate a focus on containing the fire to prevent spread to nearby vegetation or other vehicles.

Devon and Somerset Fire and Rescue Service confirmed their rapid response to the incident. A spokesperson for the fire service stated they received a call at 8:03am precisely. Two appliances—from Greenbank and Plympton—were mobilised immediately and were still actively engaged at the scene as of 9:03am.​

Which Fire Stations Responded to the Incident?

The fire service deployed crews equipped with hose reel jets and breathing apparatus to tackle the blaze effectively. As per the spokesperson, these tools are standard for vehicle fires involving potential toxic fumes or intense heat. The Greenbank and Plympton stations, both local to Plymouth, ensured a swift arrival, minimising risks to surrounding traffic.​

In similar past incidents on the A38, such as a crane fire reported by BBC News, fire crews from comparable stations have extinguished blazes within an hour, though today’s ongoing presence suggests persistent challenges. National Highways has noted traffic stoppages in affected lanes during such events to prioritise safety.

Why Was the Marsh Mills Slip Road Closed?

Police presence at the scene prompted the closure of the slip road off the A38 onto Marsh Mills roundabout, as explained by the fire service spokesperson. This measure prevents unsafe access for oncoming traffic amid the fire and firefighting operations. Inrix traffic reports corroborate this, highlighting the slip road’s full closure to all vehicles.​

Devon and Cornwall Police have not issued a specific statement on this incident yet, but standard procedure for A38 fires includes such closures to facilitate emergency access and protect the public. Eyewitness accounts from Plymouth Live’s social channels describe stationary traffic building rapidly post-closure.

How Severe Are the Traffic Tailbacks on the A38?

Tailbacks are stretching along the A38 itself, exacerbated by drivers diverting via subsidiary routes like Dark Lane and Plympton areas. Inrix detailed that the closure has led to queueing traffic well beyond the immediate site. Motorists attempting to reach Plymouth city centre are rerouted towards the Manadon roundabout, intensifying congestion on Outland Road and Alma Road.​

Local Facebook groups, such as Roads Devon Dorset Somerset, have posted updates on blocked eastbound lanes due to similar vehicle fires, with delays rippling into adjacent junctions. Plymouth Highways Twitter (now X) archives show historical tailbacks from Manadon slip road fires extending onto Tavistock Road. Current estimates suggest journey times into Plymouth have doubled during peak hours.

What Diversions Are Recommended for Drivers?

Authorities anticipate increased use of the Manadon roundabout as the primary alternative entry to Plymouth city centre. This shift is likely to overload Outland Road and Alma Road, as warned by fire service updates. Inrix advises checking live maps for real-time congestion and suggests avoiding the area where possible.​

Plymouth City Council, in response to prior A38 disruptions, has urged drivers to plan alternative routes via less impacted roads. RAC traffic news recommends monitoring the A38 Devon Expressway stretch from Exeter to Plymouth, notorious for rush-hour jams at junctions like Marsh Mills. Diverted traffic may encounter further delays at St Budeaux or Weston Mill interchanges.

Are There Any Injuries from the Car Fire?

No injuries have been reported in connection with this morning’s car fire, according to initial fire service communications. The spokesperson focused on operational details without mentioning casualties, indicating the vehicle was likely empty or the driver had exited safely. BBC coverage of a comparable Devon lay-by vehicle fire also noted no casualties.

In contrast, other A38 incidents, like a multi-vehicle accident referenced in Exeter social media, have involved closures but not specified injuries here. Devon and Cornwall Police would confirm any welfare concerns if applicable, as in past Plympton-area responses.

What Do Eyewitnesses Say About the Scene?

Dramatic images from passengers show the white vehicle’s engine compartment engulfed in flames, with smoke billowing across lanes. As shared by Ashleigh Worth in This is Exeter’s Facebook post, tailbacks formed almost immediately. Plymouth Live has aggregated similar footage from vehicle fires between Deep Lane and Marsh Mills, describing standstill conditions.

Facebook updates from Plympton Podcast highlight ongoing closures post-fuel spillage in analogous events, with plumes of smoke mirroring today’s visuals. YouTube videos of A38 rush-hour fires capture the chaos, crediting Devon and Somerset Fire and Rescue Service for containment.​​

When Will the A38 Reopen After the Fire?

Fire crews were still on scene at 9:03am, suggesting clearance could extend into late morning. Past BBC-reported fires on the A38 near Plympton or Efford saw westbound lanes reopen within 90 minutes post-extinguishment. National Highways typically manages lane reopenings once police lift restrictions.

Inrix live feeds will provide the latest on slip road status, with full reopening dependent on debris clearance and safety checks. Plymouth Plus and similar outlets track recovery timelines for A38 blockages.

How Does This Fit Into A38’s History of Incidents?

The A38, a key trunk road from Exeter to Plymouth, frequently sees disruptions at Marsh Mills due to its high volume. RAC identifies it as prone to congestion at Manadon and Marsh Mills junctions. Recent events include a 2026 crane fire closing westbound lanes, a South Brent car fire, and overturned lorries prompting Environment Agency involvement.

Holsworthy Post detailed a January serious incident closing westbound from Marsh Mills to Manadon. These patterns underscore the route’s vulnerability during rush hours, with fire services repeatedly mobilised.

This incident highlights ongoing challenges for commuters on this vital artery. Emergency services continue to prioritise safety amid the disruptions.
