Dyfatty Street is down to one outbound lane — and likely to stay that way into Monday — after a huge fire tore through an industrial unit on Saturday, sending black smoke across Swansea.
Drivers face lane closures into Monday’s rush hour after a major fire ripped through an industrial unit on Dyfatty Street in Swansea.
The fire broke out at around 12.30pm on Saturday, sending a plume of thick black smoke over the city centre that could be seen for miles around.
The unit — used as a vehicle workshop, with cars parked tightly around the building — was engulfed, with flames bursting through its roof as firefighters trained hoses on the blaze.
Mid and West Wales Fire and Rescue Service sent ten appliances — six main pumps, two water bowsers, an aerial appliance, a high-volume pump and an incident command unit.
A fire service spokesperson described it as “quite a large scale incident for us”.
People living nearby were told to keep doors and windows closed, with South Wales Police warning of heavy smoke around the Matthew Street flats and closing Dyfatty Street in both directions.
The fire was brought under control by around 4pm, the service said.
The building was left severely damaged — the aftermath pictures show its roof largely destroyed — but crews stopped the flames spreading to the neighbouring Enterprise Rent-A-Car premises.
No injuries were reported. The cause has not been confirmed, and the fire service said further investigations would follow.
The closure brought parts of the city centre to a standstill on Saturday afternoon, with traffic backing up on High Street and Carmarthen Road as drivers diverted.
Swansea West MP Torsten Bell urged people to stay away while emergency services worked, describing it as “a very significant event” in a video posted on social media.
Swansea Council said on Saturday evening that crews were dampening down the fire and that the road surface itself was being assessed for damage.
By 8.45pm the road had fully reopened to inbound traffic, with one lane running outbound.
But in a further update the council said the outbound side would stay at one lane while the building’s owner has its condition assessed — and was unlikely to fully reopen on Monday.

Drivers heading out of the city centre on Monday morning are being advised to consider alternative routes.
The fire struck at the heart of an area midway through a major turnaround — Dyfatty sits within a £20m, decade-long UK Government-funded drive to transform the neighbourhoods north of the railway station, and less than a fortnight ago a row of long-empty units reopened as the Dyfatty Junction community hub.
Residents are currently being asked to help shape the next phase of the area’s regeneration.
