I am also wondering the same things. I found it on another website and it says it is located on private property. I emailed the site and asked who i would need to contact for permission to visit if needed. Havent heard anything back yet. I have also been to moonville and i live nowhere near it. Glencoe tunnel is 10 min away and for 35 years i didnt know it was in the area. I plan to visit it in the coming weeks. If no one will answer me im just going to go and if i get stopped i get stopped. I just want to take photos and visit.
My wife and I would like to know if you can visit the Glencoe tunnel. I have searched and can not find anything that specifically says yes or no. Any information about visiting the tunnel would be greatly appreciated. We have been to Moonville and King's Hollow tunnels.
Looking on Belmont County GIS, it is apparent that this tunnel lies on private property. Owner information can be found through GIS resources.
