GOWERTON: Council still investigating cause of Cecil Road sinkhole — one month after residents first raised the alarm

The cause of the sinkhole that opened up on Cecil Road in Gowerton remains unknown, Swansea Council has confirmed, with temporary traffic lights now in place while highways teams continue to investigate — almost a month after residents first warned that the ground was sinking.

The local authority confirmed in a statement to Swansea Bay News that one lane of the B4296 between Gowerton and Dunvant remains controlled by temporary lights while officers work to establish what is causing the road to give way. Repairs will follow once the cause has been identified.

Council statement

Responding to questions from Swansea Bay News, the council said its highways team had attended the site after reports of a sinkhole forming at the junction of Cecil Road and Garrod Avenue.

“Our highways teams have recently attended Garrod Avenue/Cecil Road, following reports of a sinkhole,” the statement said.

“The road remains open to traffic and temporary traffic lights have been installed while investigations take place into the cause of the sinkhole.

“Once we have established the cause, repairs will be undertaken as quickly as possible.”

Reported a month ago

The council has now confirmed that the sinkhole was first reported to its highways team around a month ago. Officers responded to those initial reports and carried out a patch repair at the time — but the ground continued to move, opening up further over the bank holiday weekend and reaching the point at which one lane had to be closed and temporary lights installed.

The earliest public warning came from local residents on social media. Writing in a community Facebook group on 29 April, Gowerton resident Ramesy Awad said he had spotted a “new sinkhole appearing opposite Gowerton Comp,” describing a wet patch in the middle of the road that was visibly sinking by the day and “heading towards Garrod Avenue.”

Mr Awad said he had already reported the problem to local councillors the day before — and made what has turned out to be an accurate prediction: “Watch this space for a road closure in the near future.”

Four weeks later, that prediction has come true.

Councillors raised early concerns

In the same Facebook thread, Mr Awad confirmed he had contacted Labour councillor Cllr Louise Gibbard about the problem. He was also responded to publicly by Cllr Susan Jones, who said she had referred the matter to the council’s highways team for further checks.

Patch repair did not hold

The fact that a patch repair was carried out at the time of those initial reports — only for the ground to open up again weeks later — underlines why the council is now looking more closely at what is causing the road to subside.

A routine pothole or surface fault would normally be resolved by such a repair. The continued movement of the ground at Cecil Road suggests a deeper underlying issue, which is what highways officers are now working to identify.

Road remains open

The B4296 between Gowerton and Dunvant remains open in both directions, but drivers should expect delays through the morning and evening rush hours while temporary lights manage flow through the affected section.

The council has not yet given any timetable for completing the investigation, identifying the cause, or starting repairs.

Form for Gowerton sinkholes

This is not the first sinkhole to affect roads in the Gowerton area in recent years. In March 2024 a separate sinkhole forced the closure of another road in the area while investigations and repairs took place over the course of several days.

With the cause of the Cecil Road sinkhole still unknown and no timetable for repairs, residents and commuters using the B4296 face an indefinite period of disruption — a month after the first warning signs were spotted, and despite an earlier attempt to patch the road over.

GOWERTON: Sinkhole closes lane on main route to Dunvant — commuters warned to expect delays as month-old warning becomes reality

Drivers using one of the main routes out of Gowerton are being warned to expect delays after a sinkhole opened up on the road heading towards Dunvant.

The hole appeared on Cecil Road — the B4296 — just south of Gowerton Comprehensive School’s main gate, heading in the direction of Dunvant.

Lane closed, lights in place

Temporary traffic lights have been put in place at the site, with one lane closed off around the hole. Officers from South Wales Police were on the scene yesterday evening with vehicles positioned to manage traffic past the closure.

Cllr Andrew Williams, who represents the neighbouring Penclawdd ward and serves as Swansea Council’s Cabinet Member for Development, also confirmed the closure on Facebook last night, alerting residents to the disruption and warning that delays are likely during the morning commute.

In a post on a local community group, Cllr Williams said temporary lights had been installed and one lane was closed, adding that highways engineers were expected to attend in the morning to assess the damage.

A separate report from local resident Paul Terry, shared in another Gowerton community Facebook group, also confirmed the hole had appeared roughly 200 to 300 yards past the school’s main gate heading towards Dunvant.

Spotted weeks ago by local residents

The Cecil Road sinkhole did not appear overnight. A post in the Gowerton Residents Facebook group on 27 April flagged a “wet patch sinking day by day in the middle of the road heading towards Garrod Avenue,” opposite Gowerton Comprehensive School — the same spot where the road has now collapsed.

Local resident Ramsey Awad, who flagged the deteriorating road surface, said at the time he had passed the warning on to local councillors and predicted a road closure “in the near future.”

Replying in the same group, Cllr Susan Jones — Independent councillor for Gowerton ward and the newly-named Deputy Lord Mayor of Swansea — said she had passed the matter on to Swansea Council’s Highways team for inspection.

Swansea Bay News has approached Swansea Council to ask what action was taken between the original report and the road’s collapse.

Key commuter route

Cecil Road forms part of the B4296, one of the principal routes linking Gowerton to Dunvant, and continues as Garrod Avenue as it heads south towards Dunvant village.

The road carries significant volumes of commuter traffic during morning and evening peaks, with parents and pupils heading to Gowerton Comprehensive School also affected.

Alternative routes between the two villages are limited, with most options involving narrow single-track lanes — meaning traffic is likely to back up at the temporary lights through the morning rush.

What happens next

Highways engineers from Swansea Council are expected to visit the site this morning to determine the cause of the sinkhole and the scale of repairs required.

Sinkholes on residential roads can be caused by a range of factors, including failure of underground utility infrastructure, water main leaks, or the collapse of older drainage culverts. The “wet patch” reported by residents weeks ago will be of particular interest to engineers in determining the cause.

The duration of the closure will depend on what is found beneath the surface. Some sinkhole repairs can be completed within a single working day; others — particularly those linked to deeper infrastructure failures — can require lane closures lasting days or even weeks.

Swansea Council has been approached for an updated statement.

This is a breaking story. Swansea Bay News will update as further information becomes available from the council and highways engineers.
