Hi guys,
Found your website just the other day whilst trying to find out a little more about Abernant Tunnel. Yesturday I paid a visit to the Eastern portal. Went on the mountain bike so didnt enter, but I was really impressed. Impressed enough to cycle across the top of the mountain to visit Cefn Glas tunnel aswell. So thanks for providing the details to find both.
Anyway, back to the point of this topic, is there a reason why most of the tunnels around this area closed in the 60's (or more to the point 1964)
Cheers
Lloydy
