Ah, it is very easy to build a bridge, just do not let it bend or hog between columns, sag on one column nor twist, nor oscillate in any way. Avoid using parallel elements as in squares or parallelograms but apply triangular or zig zag structures where ever you can. Learn about forces due to vortex shedding in fluid mechanics and damp any three dimensional movements that may occur due to elasticity in materials. Learn about effects of dissimilar metals close together, creeping, rusting and paint and protection, and permanent and non permanent joints. Store potential energy in a bridge, but never let it change into kinetic energy, nor chemical, nor electric energy. Make sure to earth or ground the Bridge. Consider the safety factor required if the bridge is hit by an airbus A 380 or a Boeing 707. To build up experience from the experts, watch spiders building webs, beavers building dams and birds building nests of all types, and ants and monkeys dangling together to bridge gaps or swinging from tree to tree on flexible branches. Watch the structures of four legged animals forming arches and lintels, Giraffes for cantilevered necks, the wings of birds could be an inspiration to build bridges if you consider a loaded wing and turn it upside down. If one wants to go deeper into analysis of bridges learn whey horses when trotting cantering and galloping do it in a particular manner while Giraffes and camels move their legs in a different manner. Nature has been building bridges for a long time, but we have not been able to make anything as strong as the web of a spider not anything that can take so many reversals as the muscle or tendons.
