"Eads had to succeed in the face of conventional wisdom which doomed him to disaster. Entrenched authorities not only completely dismissed his theories, but pointed to the indifferent European experiences with what he proposed."

The Dublin to Belfast Rail Link established a vital connection between the capitals of Northern Ireland and the Republic of Ireland. The line's most notable engineering feature was the 1,760-foot-long Boyne Bridge; it represented one of the earliest uses of calculated stresses, the first large-scale use of wrought iron latticed girders, and the first full scale test of continuous beams. Tests performed on the wrought iron columns and struts were published and provided invaluable information for engineers who would design similar structures in the future.

The City Plan of Philadelphia is a seminal creation in American city planning in that it was the first American City Plan to provide open public squares for the free enjoyment of the community and a gridiron street pattern featuring streets of varying widths: wide main streets and narrower side streets. In addition this plan was the first city plan in the United States to provide for long-term urban growth. These features inspired the planners of many cities to adopt the Philadelphia Plan as a model.

Constructed to provide a safe, potable water supply for the citizens of Chicago, Ellis Chesbrough's Chicago Water Supply System was the first major system to utilize offshore intake systems. The system includes the landmark Chicago Water Tower and the Chicago Avenue Pumping Station. Its subaqueous tunnel was a pioneering effort in American civil engineering.

Between 1825 and 1847 the State of Ohio constructed 1,000 miles of canals and feeder canals, 33,000 acres of reservoir surface area, 29 dams across streams, 294 lift locks, 44 aqueducts and many smaller structures at a cost of about 16 million dollars. The network of navigable canals provided a system of economical transportation where none had previously existed; the young state, with its isolated frontier lifestyle, was transformed almost overnight into a thriving segment of the nation's economy.

Chartered in 1825, the Louisville and Portland Canal Company was authorized to construct a canal around the rapids called the "Falls of the Ohio." Construction started on March 1, 1826. The canal and first generation of locks were completed in 1830. As originally constructed, the canal was 1.9 miles long, 64 feet wide, and terminated at its lower end with a three-flight lock system with a total lift of 26 feet. Each lock chamber was 198 feet long between miter posts, with available length for vessels of 183 feet, width of 52 feet, and a lift at low stages of 8.5 feet.

Historically, a camino real (Royal Road) is defined as a road that connects Spanish capital with Spanish capital, a distinction not shared with roads connecting ordinary Spanish or Indian villages. The term Camino Real implied that the status and privileges granted to the villas and capitals it connected were extended to the main routes of travel through use by officials and others acting in the interest of the crown. Unlike ordinary Indian and Spanish villages, villas like San Antonio and others along the route had charters that prescribed royal privileges.

The first Zuiderzee Enclosure Dam ran from North Holland to the island of Wieringen, successfully barring the sea for over 50 years and protecting a large area north of Amsterdam. The total Zuiderzee project was the largest land reclamation effort in the Netherlands, developed over a period of about 80 years, beginning in 1918 and reaching completion in 1996. The huge dyke/dam was considered one of the greatest engineering feats of its time.

With the discoveries of South Africa's diamonds in the 1860s and gold in the 1880s, immigrants flooded into Cape Town and changed it into a major commercial center. Unfortunately, its water supply had not kept pace with the population growth. After several droughts and years of inadequate water supply, the Woodhead Tunnel was constructed between 1887 and 1891. When it failed to solve the water shortage problem, the Municipality of Cape Town determined that a dam and reservoir needed to be built.
