On 18 January 2024 a local resident contacted us about a ground collapse in the highway outside their property.

We worked closely with Neath Port Talbot Council to secure the site. In addition, we needed to put in place a partial road closure so we could carry out detailed ground investigations.  

Solution

Our investigations revealed that the collapse was caused by historical coal mine workings. We have therefore designed a permanent solution that will enable the road to be fully re-opened. We will now carry out this remedial work to fill the collapse and reinstate the ground to its original condition.

How this will affect local residents

There will be some inevitable disruption to local residents in the form of a road closure and a short power outage. We have provided further information about these below. We understand that works of this nature are disruptive and unsettling and will do all we can to minimise the impact on local residents.  

As we need to excavate the full width of the road, we will need to close Amman Road for up to three weeks from 2 April. We will do all we can to complete our work as quickly as possible. There will be diversions in place, and alternative bus routes. We understand that residents will still be able to access the smaller roads, but larger vehicles will have to follow a diversion of approximately 15 miles. Emergency vehicles will be allowed to access Amman Road.

Further information about the road closure can be found on Neath Port Talbot Council’s website – Road Works and Road Closures – Neath Port Talbot Council (npt.gov.uk)

For us to complete our work, National Grid also need to move a telegraph pole located near to the collapse. This will require a short power cut. The small number of residents and businesses likely to be affected should have already received notification from National Grid about this loss of power on 2 April from 09:00 to 13:00.

We thank you for your patience while we complete these works to repair the damage caused by the ground collapse and reinstate the road.
