LaGuardia Airport is hemmed in by river and roads, so designers must push the limits of a tight site by building as tall as possible. This means a vast 120-foot-long escalator is needed to move passengers between floors. But the install hangs precariously in the balance. Below ground the team battles to prevent devastating floods, while above, they build a world-first; twin 450-foot-long pedestrian bridges that allow aircraft to pass beneath.
The team digs deep into reclaimed land but hits trouble that threatens to delay the build, while iron workers fight to connect the biggest truss yet.
Moving Passengers And Planes: The team races to complete Terminal B in time for the grand opening, while a brutal snowstorm brings the airport to its knees.
