Reveals the engineering secrets behind Montreal’s Samuel de Champlain Bridge, enabling it to carry one million vehicles every week and survive extreme temperature fluctuations. Super-strong expansion joints flex to allow the bridge’s individual deck sections to expand and contract as the temperature varies between -30C in winter and 35C in summer, while pier legs poured from superdense concrete are strong enough to withstand the crushing force of thousands of tons of river ice.
