This program explores how bridges are made, with a focus on the physics used in design and construction. The elements of bridge building are explored step by step, from conception to completion - including factors such as materials used and how costs are governed by environmental, aesthetic and functional elements. These key issues are discussed by Technical Manager Cliff Sagot and Senior Structural Engineer Natalie Balcott from The Robert Bird Group. Their first hand knowledge gives an invaluable look into how these structures bring land and people together but also illustrate the shortfalls of bad design.
