"A weak bridge is admittedly more dangerous than an ugly one, but to seek strength at the lowest cost with no regard for appearance is only one degree worse than it would be to attempt a beautiful design without thought of stability." This concern voiced by the late C.D. Whitney, a distinguished engineer and designer of concrete structures, expresses the sentiment of leading engineers throughout the world. The problem is all the more immediate, perhaps, because engineering education focuses on technical and functional aspects of design with little attention to the visual impact of structures on the people who live with them day to day. Leonhhardt, Harbeson, Murray, Gloyd, and others advocate many of the same principles as guidelines for bridge designers. Some ideas common among these experts include: Proportion, refinement of form, integration into the environment, color and surface texture. Other important bridge design elements cited include craftsmanship, character, fulfillment of purpose or function, and a sturdy, safe appearance. Several authorities list order and simplicity as desirable attributes.
