Pörzberg Tunnel (Schaala bypass)

Germany

The Pörzberg Tunnel was built to ease congestion on a road which used to feed traffic to the A71 autobahn through the town of Schaala. Doka supplied 6 tunnel formwork travellers as a cost-saving and efficient way of casting new, replacement intermediate ceiling slabs. It was possible to cast one intermediate ceiling every day, while still complying with the stipulated stripping times.
