This Architectural Drawing is of General Arrangement Showing typical cross Section of tunnel. Total Height of tunnel is 6373 and width is 6250. A canal tunnel is a tunnel for a canal. The building of a canal tunnel is crucial to help a waterway that is normally used for shipping cross a difficult section of terrain. They are also constructed to reduce the dependency on canal locks. A longer underpass containing a road, canal or railway is normally called a "tunnel", whether or not it passes under another item of infrastructure. An underpass of any length under a river is also usually called a "tunnel", whatever mode of transport it is for.
