Precast Model Bridge

Print your own realistic, to-scale model of a common three-span precast concrete bridge. This design is fully 3D printable and segmented into pieces (girders, bents, and piles) for easy printing and assembly. The model is scaled such that 8 inches on the model represents 28 feet of the actual structure, making it a perfect educational tool or a detailed display piece for civil engineering enthusiasts, educators, or model builders.
