Construction for the Laguna Garzón Bridge began in September 2014 and ended in December 2015. [1] It cost $10 million to build, 80 percent of which was provided by Argentine real estate developer, Eduardo Costantini. [5] To build the bridge, 450 tons of steel, 500 cubic metres of concrete, and 40,000 metres of cables were used. [5]
From the Post-War period into the early 1980s the U.S. Army and its NATO and other allies employed three main types of pontoon bridge/raft. The M4 bridge featured a lightweight aluminum balk deck supported by rigid aluminum hull pontoons. The M4T6 bridge used the same aluminum balk deck of the M4, but supported instead by inflatable rubber ...
It was used until January 1929, when a toll-free bridge of concrete and steel replaced it at a cost of $600,000. Once considered the longest pontoon bridge in the world at 2,150 feet, its original construction cost $35,000. The original reason for the bridge was the hauling of cotton bales considered vital to the railroad that owned it.

There were two main types—the French-designed wooden bateau (known in the army as a "Cincinnati pontoon") and the Russian pontoon, a canvas boat.
By the end of February 2015, enough of the new bridge was in place to block tall ships that used to pass through a drawspan in the Rosellini Bridge. [32] In early July 2015, the westernmost floating pontoon was moved to make room for the installation of the west end of the bridge; on July 8, 2015, all longitudinal pontoons for the new bridge ...
