This model (not to scale) is an interpretation of a Leonard da Vinci study of a portable bridge. Initially based on Da Vinci's design found in the Codex Atlanticus, the model was designed based on two repetitive modules. Leonardo designed many bridges, but this is certainly the most brilliant for its simplicity, practicality and tactical efficiency. Namely because it is transportable and comparable (albeit in reverse order) to the famous Bailey bridge of World War II (which, moreover, was based on the removable bridge created by the engineer, Neapolitan Alfredo Cottrau in the second half of 1800). Leonardo's bridge is composed of simple circular section beams, which are assembled without the use of ropes or shaped joints: the weight of the bridge is sufficient to exert the necessary pressure, because the upright beams, closing in a scissor-like fashion, block the crossbars, thus preventing the structure from collapsing. Moreover, the stability of the bridge increases with an increasing load. 

There are 35 pieces, including some leather finished parts. Glue is recommended to join some pieces when assembling this model. Illustrated instructions in Italian and English are included with the kit. See the additional tab on the product page to view the instructions online.
