When it first opened a century ago, the Panama Canal transformed international trade by providing a shortcut between the Atlantic and Pacific oceans. But today, in the age of ever-expanding megaships, almost half the world’s container vessels are too large to fit through it.
In 2009, engineering firm MWH Global began redesigning the canal—evolving it from concept to construction, and setting new standards for how massive, multinational civil infrastructure projects are designed, managed, and built.
This summer, the expanded Panama Canal will open—and the impact of this $6 billion megaproject will reshape our global transportation infrastructure for the next century.
The expansion of the Panama Canal is one of the largest and most ambitious construction projects in the world.
MWH Global’s new design will increase the capacity of passing ships from 4,600 containers to 12,800. It’s a quantum leap. The project will use the equivalent of 26 Eiffel Tower’s worth of steel, and enough concrete—190,000 tons—to construct the skyline of a major city.
What is the Panama Canal?
A 48-mile-long passageway that connects the Atlantic and Pacific oceans.
Why was the Panama Canal built?
To ship goods between the two coasts quickly, cheaply, and safely.
Who built the Panama Canal?
After an initial attempt by France, the U.S. built it from 1904-1914.

The Panama Canal rises 85 feet above sea level. That’s about nine stories high.
To pass through the canal, a ship enters a lock—think of it as a massive boat elevator. Once the ship enters the lock, water from a manmade lake is pumped in, which lifts the ship. The vessel then sails across the channel and is carried back down by locks on the other side.
It’s a major engineering and construction feat to lift and guide today’s supersized ships—over 1,000 feet long and 40 feet high—through the canal and then back into the ocean, all without damaging the surroundings. MWH Global was up for the challenge.
26m / 85ft
Expand existing channels:
Widen 21.3 m / 70 ft
Deepen 5.4 m / 18 ft
Lengthen 121 m / 400 ft
Create a new channel, with 3 new lock chambers on each side
Raise the maximum operating level of Gatun Lake, the primary water source for the locks
How many engineers does it take to change a canal? More than 400, all of them under pressure to stay ahead of construction.
"The most daunting challenge was meeting the high design performance requirements. This is the Panama Canal. We couldn’t afford to make a mistake. And the clock was ticking."

Can a project this massive also be eco-conscious?
It had to be. Gatun Lake not only helps operate the locks, it’s a major source of drinking water for Panama. Expanding the canal passageway would require the use of significantly more fresh water, but MWH Global had to find a way to make it happen using less water.
How did they do it?
MWH Global designed three new storage basins—the largest in the world—that will:
When the Panama Canal expansion opens in summer 2016, it will spark a dramatic change in the way cargo is moved around the world.
