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.
