The plans were approved in 1711, and work began but was delayed by the second Battle of Villmergen. In the spring of 1713 work restarted under the direction of Bern's city architect Samuel Jenner, but with a tunnel instead of the unfinished cutting. Work was finished by the end of the year, but in 1714, the river started to enlarge the channel, causing the tunnel to collapse and creating today's "Kanderschlucht" or Kander canyon.
