Built on logs in 1820, then upon tarred barrels in 1884, rebuilt using plastic barrels filled with styrofoam in 1978, carries light automobile traffic. This bridge was closed for replacement spring of 2008, and the current iteration makes use of fiber-reinforced polymer pontoons.
Geographically, Czech log-boat sites and remains are clustered along the Elbe and Morava rivers. [18] Poland is known for so-called Lewin-type log-boats, found at Lewin Brzeski, Koźle and Roszowicki Las accordingly, and associated with the Przeworsk culture in the early centuries CE.

The simplest form of all ancestral Austronesian boats had five parts. The bottom part consists of single piece of hollowed-out log. At the sides were two planks, and two horseshoe-shaped wood pieces formed the prow and stern. These were "sewn" together with dowels and lashings. They had no central rudders but were instead steered using an oar ...
A pontoon boat is a flattish boat that relies on floats to remain buoyant. These pontoons (also called tubes ) contain much reserve buoyancy and allow designers to create large deck plans fitted with a variety of accommodations including expansive lounge areas, stand-up bars, and sun pads.
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.
A pontoon boat is a flattish boat that relies on nautical floats for buoyancy. Common boat designs are a catamaran with two pontoons, or a trimaran with three. [2] In many parts of the world, pontoon boats are used as small vehicle ferries to cross rivers and lakes. [3] An anchored raft-like platform used for diving, often referred to as a pontoon
World War II recruiting poster for the U.S. Army Corps of Engineers. An Engineer Light Ponton Company was a combat engineer company of the United States Army that served with U.S. Army ground forces during World War II. [1]
The bridge is constructed on a standard frame and then boomed onto six pontoons then it is bolted on The pontoons have two water propulsion units, which are used to steer the ferry when it is in water. The engines that are used to power the propulsion units are also used to operate the hydraulic rams, which raise and lower the two ramps. [1]
