The Woodsmith Mine Tunnel (also known as a Mineral Transport System [MTS]) is a 23-mile (37 km) long tunnel that will stretch between Woodsmith Mine at Sneatonthorpe near Whitby in North Yorkshire and the Wilton International complex on Teesside, England. The tunnel has been in development since 2016, but cutting of the tunnel bore did not
Since its inception, Capitol Tunneling crews have installed more than 125,000 feet of hand-mine tunnel, ranging from 4 feet to 18 feet in diameter. Capitol Tunneling also provides the single-pass and two-pass methods of machine mine tunneling. Machine mining utilizes a Tunnel Boring Machine (TBM) to mechanically excavate the face of the tunnel.
