Floating Bridge, Kyrkby (No. 2)

A pontoon bridge (or ponton bridge), also known as a floating bridge, uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry.

Most pontoon bridges are temporary and used in wartime and civil emergencies. There are permanent pontoon bridges in civilian use and carry highway traffic and allowing ships or boats to pass on the river or lake being crossed. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored piers. Such bridges can require a section that is elevated or can be raised or removed to allow waterborne traffic to pass.

Pontoon bridges have been in use since ancient times and have been used to great advantage in many battles throughout history, such as the Battle of Garigliano, the Battle of Oudenarde, the crossing of the Rhine during World War II, and during the Iran–Iraq War's Operation Dawn 8.

Floating Bridge, Kyrkby (No. 1)

A floating bridge rises and falls with the water level. In the past this was a common way to build bridges across Dalälven. The municipality of Gagnef is crossed by two rivers, Österdalälven and Västerdalälven, and it has influenced the district in a special way. The water provided opportunities for fishing and transportation and all the larger villages in the municipality is located along rivers. As the years went by people started to be more dependent on transporting their animals, goods and themselves across the rivers. The first real transportation across the rivers were ferries that were rowed and pulled with ropes across the rivers. during the 1600's many ferries were replaced by floating brigdes. It is said to have been 11 floating bridges across Dalälven, now there are only these two left in Gagnef and Österfors.
