A Conisboro’ Engineering Problem
This photograph shows the elaborate tunnelling necessary in connection with the new sewerage scheme at Conisborough, described in our last issue by Mr. H. Thirlwall, engineer and surveyor to the Conisborough Urban District Council.
This is a view of the tunnel from the Sheffield Road end. The tunnel is 88 ft, long and four feet square.
