View from the bridge at Håverud, Dalsland, Sweden.The canal boats are carried above the stream via the waterway to the left.
The Håverud Aqueduct was created by the famous canal builder Nils Ericson. Due to the special geological conditions at Håverud it was not possible to build an ordinary lock there. The rock was loose, the current was strong and the fall was too great. So Ericson had the brilliant idea of building an aqueduct instead. The aqueduct is a free-hanging bridge, where the water runs through a 33.5 metre long steel channel above the rapids. The steel plates are joined with 33,000 rivets. Thus far, not a single rivet has had to be replaced.
