Built between 1819 and 1826, the Menai Bridge was the major structure on Britain's strategically important Holyhead Road connecting London with Holyhead and by sea to Ireland. Designed by Thomas Telford, the bridge's main span was 579 feet from tower to tower, the longest that had ever been attempted at this time. He used four sets wrought-iron eyebars to suspend the deck. These were made by William Hazledine at his Upton forge near Shrewsbury. Each bar was carefully tested in his Coleham shops before being pinned together and lifted into place.

The Tehachapi Pass Railroad Line was cut through solid and decomposed granite by about 3,000 Chinese laborers using nothing more than picks, shovels, horse drawn carts, and blasting powder. This line, which rises from the San Joaquin Valley and through the Tehachapi Mountains, originally included 18 tunnels, ten bridges and several water towers to accommodate the steam locomotives. Completed in less than two years, it was part of the final line of the first railroad to connect San Francisco with Los Angeles.

The idea of creating a canal linking the Mediterranean Sea to the Red Sea is a very old one that dates back about 4000 years to the ancient Egyptians. They thought of linking the two seas by using the River Nile and its branches. It was this very old desire that led to the digging of the present Suez Canal.

Sculptor Frederic-Auguste Bartholdi is credited with bringing the concept of the Statue of Liberty to fruition, deriving inspiration from the 19th-century penchance for grandiose monuments. He originally designed the statue for placement at the Suez Canal, but the project was never commissioned. After a promotional trip across America, Bartholdi's ideas finally took hold in 1874, and a Franco-American coalition was formed to fund the project, with the Americans building the base and the French the statue.

The scheme virtually reverses the flow of the Snowy River from its natural course toward the ocean and directs it inland. The entire complex includes 16 dams, seven power stations (with a production capacity of 3,740,000 kilowatts), over 90 miles of tunnels, a pumping station, and 50 miles of aqueducts.

This was one of the first power facilities to demonstrate the feasibility of long distance electric power transmission. Through an elaborate switchboard at the main station, tied to similar boards at substations, a complete circuit was created to drive an electric motor 153 miles from the generator a remarkable distance at that time.
