Long-span bridges include a lot of space between their supports, and that allows them to cover wider gaps like deep valleys and very wide rivers. Supports are critical for bridges, so when there isn’t much space to include them, bridge designers and engineers need to spend additional time calculating estimated load and how to includes enough support for the long bridge using minimal space. This advanced structural design, coupled with materials and construction techniques, can help ensure that two distant points are safely connected. Materials and Forms Long-span bridges need materials that can hold up to immense forces, but they […]
