Superb upload ,i walked this tunnel a couple of times in the late 80's those open drain culverts are evil if you didn't spot them , i would suggest before total work is done having a open day walk through ,charge say a fiver and donate to local charity
Nothing to stop anybody finding their own disused tunnell .theres plenty of em all buried and all your doing is taking advantage of sombody elses work that nobody else has been allowed to know about
