A massive construction project has been underway deep in the heart of the Schnecktal valley area in Germany. From the surface, though, you would never be able to tell. The majority of the work is underground as a joint-venture team led by German contractor Wayss and Freytag Ingenieurbau AG builds the nearly seven kilometer (4.3 mi) long Finne Tunnel. After a few years of tunnel boring operations, the contractor is at work finishing the interior of the tunnel, slipforming first the tunnel’s floor and then a walkway with their GOMACO Commander III.
