S01E07 Building Hong Kong's Airport

Hong Kong's bustling airport was struggling to keep up with the city's growing traffic demands, prompting the urgent need for a new facility. The solution lay 16 miles out in the ocean, where a state-of-the-art airport could be constructed. However, this ambitious project required the development of 22 miles of new superhighway. Initially expected to take decades to complete, engineers were surprisingly tasked with finishing the entire project in just 7 years.
