From amazing ancient Roman aqueducts and arch bridges, romantic Renaissance spans, 19th-century railroad crossovers, to monumental marvels of our time, bridges played a key role in the human quest to connect and unify. We'll trace the history of bridge types, including suspension, arch, beam, truss, and cantilever designs.

It was an engineering feat of almost miraculous proportions and a design of spectacular elegance. Rare photographs and behind-the-scenes stories recall the politics, the struggles, and the tragedies that made possible "the Eighth Wonder of the World".

More than 50 years after its construction, the Golden Gate remains one of the world's great engineering marvels. It took 25-million man-hours and 80,000 miles of cable to complete. But the cost in human life proved even greater.

Until recently, the Mackinac Bridge was the longest suspension bridge in the world. One of the top engineering marvels of the 20th century, the bridge spans the 4-mile wide straits of Mackinac, where Lakes Huron and Michigan come together. The Mighty Mac connects the pastoral northern mainland of Michigan with the state's heavily forested Upper Peninsula and stands as a testament to the dreams, determination, and hard work of a small few who created a true masterpiece of modern engineering.

Much of New York City's history can be viewed via its bridges--all 18 that connect Manhattan Island to its neighbors. Join us for a look at these architectural masterpieces from the age of iron and steel; and, see how they have changed destinies, linking some to opportunity, others to ruin.

In a battle against the ferocious Atlantic or safe passage through waters where ships wrecked and lives were lost, it was an engineering feat that many believed impossible. This is the story of the Cape Cod Canal and the men who braved the natural elements and the Great Depression by venturing into new engineering territory. In 1909 excavation began on what would become one of the greatest success stories of our time. the evolution of the Cape Cod Canal into what it is today--a major commerce and recreational route of the Intracoastal Waterway--is a tale of determination, ingenuity, and the American spirit. Through historical photographs and expert interviews, the Canal's story unfolds, and while traveling along on an Army Corps of Engineers Patrol Boat and Coast Guard vessel we see firsthand what happens on the Canal on a daily basis. And we meet the people who make the Canal and its bridges functional and safe, keeping the legacy of the early engineers alive.

Chronicles one of the most incredible engineering feats of all time: construction of the 51-mile canal that took ten years to build and employed over 40,000 workers, 6,000 of whom died of yellow fever, malaria, and other horrors. An earlier, nine-year attempt by the French ended in failure and cost 20,000 lives.

Since the ancient pharaohs' time, the Isthmus of Suez has been the gateway to trade between East and West. It's thought that the pharaohs could connect the Red Sea with the Mediterranean using a system of small canals; but the desert sands buried them. Not until mid-19th century did mankind readdress the problem. Since its completion in 1869, the Suez Canal has been a vital link in world trade and a point of controversy in geopolitics. Today, more than 20,000 ships transit the canal yearly.
