Bridges have expanded empires, connected communities and won wars. Join us as we unearth the foundations of these mighty structures from across the world. This episode charts the engineering advances that have culminated in the spectacular bridges of our modern age and how these breakthroughs sent ripples beyond simply a structural dimension. Uniting otherwise separate land has enabled communities to travel, societies to reach their food source and armies to invade territories Follow the effects of the industrial revolution; the awe-inspiring consequences of ambitious engineers and mass produced materials. The following centuries would see bridge design become even more impressive as longer and stronger bridges were engineered into existence. Step back in time to explore the different forms and functions of these majestic structures.
