Correspondence shared by Uplands councillor Peter May reveals that mining records show a historic mine feature located approximately 100–150 metres north of the collapse site. The council is now contacting the Coal Authority for detailed plans and considering a full geotechnical survey to check for other voids in the area.
Void under road larger than first thought
The latest update follows a site meeting between council officers and Dŵr Cymru, where a void of at least 8 metres in length or depth was discovered beneath the road surface.
According to the council’s internal note, the void is not linked to a previous water leak but may have caused the leak that was repaired last week. The ground remains unstable, and Heras fencing has been installed to prevent access.
A camera survey is scheduled for tomorrow morning to assess the full extent of the damage.
Road closure and safety measures
Brynymor Crescent remains closed, and a full diversion route is being arranged. The void is located around 10 metres from the nearest properties, and while there is currently no immediate risk to residents, the council says it will know more once survey results are available.
Cllr May has been sharing updates via social media and said he would continue to keep residents informed as investigations progress.
