The 242 yds long Mierystock tunnel was on the Lydbrook branch of the Severn & Wye Railway and last saw a passenger train in 1929.Tragedy struck during 1893 when a ganger surrendered his life to a locomotive.The Northern End off the tunnel was covered over with waste and this side bricked up as it was seen as unsafe back in the 1970s On 1st February 2005 hard graft was heard rumbling through the trees. Financed from their own pockets Locals tried to get the tunnel reopened for cyclists to use and cleared colliery waste covering the northern entrance to reveal the Dated key stone,but they were soon stopped.ITV’s People’s Millions - a competition backed by lottery cash - was offering £50,000 grants to worthwhile community projects,A promotional film made the case for Mierystock come good when Viewers voted in their thousands ,the cheque was given live in a local pub,The men then cleared 30,000 tonnes of colliery waste. But the tunnel remains bricked up after all the hard work the locals put in so cyclists could bypass the busy road, you can find a little bit about there work from the link above.....It's main use now! seams to be making a easier route for a brook and a pretty water fall.
