Sillankäyttökohteet refers to the various purposes and applications for which bridges are constructed and utilized. Fundamentally, bridges serve as critical infrastructure to overcome natural or man-made obstacles, facilitating the movement of people, goods, and services.

The primary use of bridges is for transportation. This includes road bridges that carry vehicular traffic, allowing for the efficient transit of cars, trucks, and buses. Railway bridges are designed to support the weight and movement of trains, connecting distant locations and enabling freight and passenger rail services. Pedestrian bridges, also known as footbridges, are built specifically for people to cross, often in urban areas, parks, or over busy roads, enhancing safety and accessibility. Bicycle bridges are increasingly common, offering dedicated and safe routes for cyclists.

Beyond simple transit, bridges can serve other functions. They can be part of utility corridors, carrying pipelines for water, oil, or gas, or housing electrical cables and telecommunications lines. In some instances, bridges are designed as observation points or recreational areas, offering scenic views and opportunities for leisure. Historic bridges may also be preserved as cultural heritage sites, recognized for their architectural significance or historical importance. Furthermore, bridges can play a role in flood control or as emergency evacuation routes. The specific design and type of bridge are determined by its intended use, the environment it spans, and the load it is expected to bear.
