With the construction evolution and consequent roads and railways progressive development, emerged the need for the population to make crossings, not only to overcome geographical obstacles, but also to reduce the necessary travel time. However, one of the major problems until today has been the crossing of navigable waters. As one of the keys means of global transport, server navigation could not be less important than the construction of bridges, which would affect its course. It was then necessary to find a solution that would enable navigation of rivers and at the same time their crossing. Since building bridges with adequate clearance for the passage of ships required a more elaborate work in terms of very high inclination, movable bridges became the most viable solution to this dilemma, despite all all the challenges on their design. Nevertheless, movable bridges have not always had this purpose. In the Middle Age, these were used for protection against enemy's armies. The design of movable bridges, have primary explored over the last century the typical three types of movable bridges, bascule; swing; and vertical lift. Regardless of this, innovative solutions are increasingly taking form.
