This bridging system was widely used by the USA in WW2 to cross rivers and streams.
You could add boats and rodaway sections as needed and could be used to cross very large rivers like the Rhine.
This was carried on the Brockway/Corbit 666 tucks that we also make.
This set contains 3 inflatable pontoons, 2 roadway sections, 4 metal ends and 6 roadway supports.
Extra boats and roadway sections can also be purchased, POA.
