Channel 5 - Building the Billion Pound Mega Bridge (2020)

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.
