Natural Strength: The Durability of Timber Bridges
The strength of timber bridges comes from the natural properties of wood and advanced construction techniques. Hardwoods like oak and softwoods like Douglas fir provide excellent load-bearing capacity, making them ideal for bridge construction. Unlike steel, which is prone to corrosion, timber naturally resists certain environmental threats. Additionally, modern treatments, such as pressure impregnation with preservatives, enhance wood’s resistance to decay, insects, and fungal growth. Timber’s natural flexibility allows it to withstand Temporary Bridges dynamic loads, including heavy traffic and environmental stresses like wind and earthquakes. Furthermore, engineered wood products, such as glulam (glued laminated timber), increase the strength and consistency of timber bridges, ensuring long-lasting durability.
