Stone has been a reliable material for bridge construction for centuries due to its high compressive strength and minimal need for complex connections. This allows for durable arched footbridges with standard piers. However, advancements in bridge technology have shifted towards steel and concrete due to modern requirements like loading and span. Concrete is often reinforced to handle tensile loads, enabling more diverse bridge designs. For larger spans, prestressed cables are utilized to maintain structural integrity.

Despite being less popular in the early 20th century, stone is regaining interest for its sustainability and durability. With modern techniques like digital modeling, it can be effectively used alongside timber for bridge designs. This combination ensures ease of maintenance and aesthetic appeal, making it a viable option for projects like the Lower Thames Crossing.

Our proposal takes mainstream technology, including the opportunity to digitally analyse unwanted quarry stone, to provide a sustainable, structurally efficient, easily maintainable and adaptable solution to footbridges
