You're a civil engineer. Four bridges need to go up. Only you can decide where they go.
Students get a chance to design and actually build four types of bridges.
This site also includes a great list of resources and a teachers guide. Rules, winning design photos, and various other statistics are included in this site. An ordinary un-inspiring bland concrete bridge is transformed into a work of art by community members. See what role aesthetics play in the design process. It is excellent for teaching bridge design, loads, stresses, compressive and tensile failures, etc.
