Costain have advised that they are doing some blasting to create the split-level dual carriageway section during Fri-Sat 29th-30th September and that access to Ogof Nant Rhin will be closed while this is happening - just for those two days. Notices will be posted at the cave entrance, it is on the CCC website, and CCC will email all member club contacts.
The vibration levels will not exceed those created by earlier tests reported in the CCC newsletter for Oct 2016 here http://cambriancavingcouncil.org.uk/pdf/newsletters/51_oct2016.pdf
Nevertheless you don't want to be underground nearby when the bangs go off.
