puente voladizo es cantilever bridges en

Bridges built using cantilevers, which are structures that project horizontally into space and are supported on only one end. In a typical cantilever bridge, two cantilever arms are joined in the center by a light suspended span. The balancing of forces of tension, or pulling, and the forces of compression, or squeezing, create a strong bridge; thus cantilever construction is employed for large spans in certain sites, especially for heavy loads.
