Leonardo carried out numerous projects for solving problems related to crossing watercourses, and the technical solutions he devised still astonish for their modernity and genius. This bridge for military use was designed during the early Milanese period. It could be quickly built by interlocking and weaving together materials that were easily found, such as logs and ropes. Because it was ideal for saving armies in need of escape, Leonardo also called it a “salvation bridge”.
The bridge is able to stand without the use of ropes, since the interlocked trunks perform the function carried out by centerings in architecture. Additionally, some of the wooden planks, anchored on the supporting structure, form a suitable walking surface.
