Assemble set series Leonardo da Vinci’s Swing Bridge design is a portable, lightweight bridge that was intended to span across a body of water so armies could cross and then quickly disassemble and tow away. By means of an articulated system of winches and wheels, the bridge was designed to rotate 90 degrees. To maintain the bridge’s balance during the opening phase, and to prevent the whole structure giving way beneath its own forward weight, da Vinci provided a caisson full of stones to act as a countermand until the bridge came to rest on the opposite bank. Equipped with a rope and wheels, the lightweight bridge was made for easy transport.
