What kind of bridge did Leonardo da Vinci design for rapid assembly and easy transport?

Leonardo da Vinci designed a self-supporting bridge for rapid assembly and easy transport.

The design appears among Leonardo’s engineering studies, where he explored bridges that soldiers could construct quickly without relying on permanent masonry. Its interlocking wooden elements were intended to support one another, making the structure practical for temporary crossings.

This bridge is sometimes confused with Leonardo’s revolving bridge, another portable military design. The revolving bridge was meant to swing across a waterway and then be moved or dismantled, while the self-supporting bridge emphasized a stable structure assembled from linked parts.

Leonardo’s bridge concepts show his interest in military engineering, logistics, and the mechanical behavior of wood. They were proposals rather than widely documented Renaissance infrastructure projects, but modern demonstrations have shown that the basic interlocking principle can work.
