The ability to change the length of the Telescopic Span allows the bridge to adapt to changing water levels or other conditions, making it useful in locations where the watercourse is prone to flooding or erosion. Telescopic spans can be a cost-effective solution for small or medium-sized bridges, as they require less material and labor than traditional bridges. The design of the Telescopic Span is simple and robust, which means that they have a longer lifespan than other types of bridges.
