The Panama Canal is considered the 7th wonder of the modern world. But today, it is too small. Now in order to fit the worlds’ growing fleet of super ships, the Panama Canal is getting a complete overhaul. This all-new, one-hour Modern Marvels takes us inside the billion dollar Panama Canal Expansion Project. With unprecedented access, this program features exclusive footage of the building of the new canal and shows us what it takes to complete one of the greatest construction projects in history. From massive explosions at the excavation site to eighteen hour concrete pours at the lock walls… from the assembly of the largest locks gates in the world to their transport on the backs of semi-submersible ships across the Atlantic… With the help of visually stunning photography and ample use of drone and time-lapse cameras, we’ll follow the building of a modernized Panama Canal and capture the impressive scale and pace of this undertaking.
