I came across this picture last week whilst searching for something completely different. I have never seen this before. It shows the viaduct on Mottram Old Road between Gee Cross and Hattersley. It states it shows the dismantling of railway tunnels, after construction of cutting and viaduct. The picture as taken by a Mr. Maurice Marshall and dates 1907.
Can anyone add any more information about this, I've never heard of these tunnels before.
