A pontoon bridge, also known as a floating bridge, is a collection of specialised, shallow-draft boats or floats, connected together to cross a river or canal. The boats are tied together with heavy ropes and weighted with anchors to hold them in place. The buoyancy of the boats limits the maximum load that they can carry. The decking may be temporary or permanent, and constructed out of wood, modular metal, or asphalt or concrete over a metal frame.

What You'll Learn
- Pontoon bridges, also known as floating bridges, are made from shallow-draft boats or floats
- The buoyancy of the supports limits the maximum load that they can carry
- Pontoon bridges are often temporary and used in wartime and civil emergencies
- Permanent pontoon bridges are used for highway traffic and can be raised to allow waterborne traffic to pass
- Boats are tied together with heavy flaxen and papyrus ropes and weighted with heavy anchors to hold them in place
Pontoon bridges, also known as floating bridges, are made from shallow-draft boats or floats
The boats are tied together with heavy flaxen and papyrus ropes and weighted with heavy anchors to hold them in place. Logs are used for the bridge's surface, and these are topped with brush and soil. There are often barriers on each side so that horses (and people) won't be spooked by walking so close to the water.
The supporting boats or floats can be open or closed, temporary or permanent, and made of rubber, metal, wood, or concrete. The decking may also be temporary or permanent, and constructed out of wood, modular metal, or asphalt or concrete over a metal frame.
Most pontoon bridges are temporary and used in wartime and civil emergencies. However, there are permanent pontoon bridges in civilian use that can carry highway traffic. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored piers.

The buoyancy of the supports limits the maximum load that they can carry
A pontoon 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. The supporting boats or floats can be open or closed, temporary or permanent, and made of rubber, metal, wood, or concrete. The decking may also be temporary or permanent, and constructed out of wood, modular metal, or asphalt or concrete over a metal frame.
The maximum load that a pontoon bridge can carry is limited by the total and point buoyancy of the pontoons or boats. The buoyancy of the supports is determined by the volume of water displaced by the pontoons or boats. The greater the volume of water displaced, the greater the buoyancy, and the greater the load that can be supported.
The weight of the decking and the weight of the vehicles or pedestrians using the bridge must be considered when determining the maximum load that a pontoon bridge can carry. The buoyancy of the supports must be sufficient to support the weight of the decking and the live load of the vehicles or pedestrians.
The design of the pontoon bridge must also consider the distribution of the load. The load must be evenly distributed across the supports to ensure that the buoyancy is not exceeded at any one point. This is particularly important for pontoon bridges with multiple spans, where the load is transferred from one span to the next.
In summary, the buoyancy of the supports is a critical factor in determining the maximum load that a pontoon bridge can carry. The design of the bridge must consider the weight of the decking, the live load of vehicles or pedestrians, and the distribution of the load to ensure that the buoyancy of the supports is not exceeded.

Pontoon bridges are often temporary and used in wartime and civil emergencies
Pontoon bridges, also known as floating bridges, are often temporary and used in wartime and civil emergencies. They are made up of a collection of specialised, shallow draft boats or floats, connected together to cross a river or canal. The buoyancy of the supports limits the maximum load that they can carry.
The boats are tied together with heavy flaxen and papyrus ropes and weighted with heavy anchors to hold them in place. An opening is left so that small vessels navigating the strait can still pass the bridge. Logs are used for the bridge's surface, and these are topped with brush and soil. Barriers are placed on each side so that horses (and perhaps men) won't be spooked by walking so close to the water.
Pontoon bridges can be made with supporting boats or floats that are open or closed, temporary or permanent, and made of rubber, metal, wood, or concrete. The decking may also be temporary or permanent, and constructed out of wood, modular metal, or asphalt or concrete over a metal frame.
Most pontoon bridges are temporary and used in wartime and civil emergencies. However, there are permanent pontoon bridges in civilian use that can carry highway traffic. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored piers.

Permanent pontoon bridges are used for highway traffic and can be raised to allow waterborne traffic to pass
Pontoon bridges, also known as floating bridges, are made up of floats or shallow-draft boats that 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. However, there are permanent pontoon bridges that can carry highway traffic. These permanent bridges are useful for sheltered water crossings when it is not economically feasible to suspend a bridge from anchored piers. They can be raised or removed to allow waterborne traffic to pass.
The supporting boats or floats of a pontoon bridge can be open or closed, temporary or permanent, and made of rubber, metal, wood, or concrete. The decking may also be temporary or permanent and can be constructed out of wood, modular metal, asphalt, or concrete over a metal frame. The spelling "ponton" in English dates back to at least 1870 and was used in U.S. patents during the 1890s.

Frequently asked questions
A boat bridge, also known as a pontoon bridge or floating bridge, is a collection of shallow-draft boats or floats that are connected together to cross a river or canal.
The boats are tied together with heavy ropes and weighted with heavy anchors to hold them in place. A track or deck is attached to the top of the boats, which is supported by the buoyancy of the water.
The maximum load of a boat bridge is limited by the total and point buoyancy of the boats. The supporting boats can be made of rubber, metal, wood, or concrete.
Most boat bridges are temporary and used in wartime and civil emergencies. However, there are permanent boat bridges in civilian use that can carry highway traffic.
