"When the load is uniformly distributed on a beam of any cross-section, it will sustain a load twice as great as when the load is applied in the middle between the supports." — Hallock, 1905

A cantilever bridge is a bridge built using cantilevers, structures that project horizontally into space, supported on only one end. For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over 1,500 feet (460 m), and can be more easily constructed at difficult crossings by virtue of using little or no falsework.

"A cantilever is a beam, bar, rod, etc., fixed at one end and subjected to a transverse stress. It has a tendency to overthrow the wall or structure to which it is attached." — Hallock, 1905

"The maximum safe load in pounds that should be allowed at the end of any cylindrical cantilever is equal to the cube of its diameter in inches multiplied by .6 of the constant given in the tale, and the product divided by its length in feet." —Hallock 1905
