A pontoon bridge is a collection of specialized, shallow draft boats or floats, connected together to cross a river or canal, with a track or deck attached on top. However, the historian Joseph Needham has pointed out that in all likely scenarios, the temporary pontoon bridge was invented during the 9th or 8th century BC in China, as this part was perhaps a later addition to the book (considering how the book had been edited up until the Han Dynasty, 202 BC – 220 AD). "By dawn on 4 April 2003, the 299th Engineer Company had emplaced a 185-meter long Assault Float Bridge—the first time in history that a bridge of its type was built in combat."[53] This took place during the 2003 invasion of Iraq by American and British forces. ./cache/en-wikipedia-org-937.html ./txt/en-wikipedia-org-937.txt
