Crews excavated over 200 million cubic yards of earth, battling challenging terrain and diseases like malaria. Completing this ambitious canal demonstrated how visionary engineering can reshape global transportation and trade.

4.1 Cutting Through 50 Miles of Land Was Not Easy

Carving out an artificial waterway through the Continental Divide that separated the Atlantic and Pacific required immense effort and sacrifice. Excavations took over a decade, with the builders facing unstable soil, landslides, floods, heat exhaustion, mosquitoes, equipment failures, and yellow fever. Overcoming these obstacles to connect two oceans with the Panama Canal was an engineering feat made possible by determination and ingenuity in the face of challenges.

5. The Golden Gate Bridge Took 4 Years to Build

The Golden Gate Bridge was the longest suspension bridge in the world when it opened in 1937 to connect San Francisco with Marin County. It took four years for crews to build the bridge’s two massive support towers rising 746 feet above the water. They also strung 80,000 miles of wire cables through the bridge towers to support the 4,200 foot main span. The Golden Gate Bridge’s beautiful design and challenging construction expanded possibilities for bridge engineering. Its iconic structure has made it a symbol of American engineering innovation.

5.1 It Was the Longest Suspension Bridge in the World at the Time

When the Golden Gate Bridge opened, its main span of 4,200 feet made it the world’s longest suspension bridge by a wide margin. It broke the previous record of 3,240 feet held by the George Washington Bridge in New York. For decades, the Golden Gate retained the title of world’s longest main bridge span. Constructing such a record-breaking structure required pushing engineering boundaries. Its success set a new standard for the design of suspension bridges worldwide.

6. 3D Printing Will Revolutionize Manufacturing

3D printing, also called additive manufacturing, is an emerging engineering technology that has the potential to transform manufacturing. 3D printers build objects layer by layer from materials like plastics, metals, or concrete based on 3D model designs. This allows engineers to quickly create complex customized parts without retooling factories. 3D printing could someday enable businesses to produce specialized products tailored to each customer’s needs.

6.1 Complex Shapes Can Be Created Quickly

One revolutionary aspect of 3D printing is its ability to construct complicated shapes rapidly. While traditional manufacturing often requires assembling multiple parts, 3D printing builds intricate designs as a single piece. This allows custom medical implants like hip joints to be tailored to fit patients’ anatomy. Parts with optimized shapes and cavities can be printed, reducing weight in aerospace applications. The complex but fast geometries of 3D printing open new possibilities across industries.

7. The International Space Station Took 10 Years and Over 100 Flights to Assemble

The International Space Station is one of the most complex engineering projects ever undertaken. The football field-sized ISS was constructed over 10 years using components ferried into orbit during over 100 rocket flights from different nations. Astronauts conducted risky spacewalks to bolt together modules and unfurl solar arrays as it circled Earth at 17,500 mph. Assembling this research outpost 250 miles high despite the challenges of space travel expanded the boundaries of engineering.

7.1 It’s Almost the Size of a Football Field

The International Space Station has a mass over 1 million pounds and spans the length of a football field from end zone to end zone. Its living and working area is over 32,000 cubic feet, equal to a Boeing 747 jet. Piecing together a structure this enormous required unprecedented orbital construction techniques. But the massive size enables cutting-edge microgravity research that would be impossible with a smaller station. Thinking big led to an unparalleled engineering accomplishment.

8. The Channel Tunnel Connects England and France Underwater

The Channel Tunnel, often called the Chunnel, is an underwater tunnel linking England and France beneath the English Channel. British and French engineers excavated 31 miles of tunnel up to 250 feet below the seabed. Massive tunnel boring machines dug through challenging chalk marl soil at a speed of nearly a mile per week. Since opening in 1994, the Chunnel has carried over 200 million passengers on Eurostar high-speed trains that zip underneath the channel. This engineering feat bridged the gap between the U.K. and mainland Europe.
