Few American cities can claim a landmark as distinctive as Cincinnati's Suspension Bridge. The Covington and Cincinnati Bridge, in 1984 renamed after designer John A. Roebling, and all the while called by locals simply "The Suspension Bridge", has been a symbol of the city since its opening in December of 1866. Images of the bridge can be seen today in all parts of the city hanging in homes, offices, restaurants, bars, waiting rooms, and as backdrops for the local television news. More than just a nostalgic decoration, the old bridge remains an important river crossing for thousands of cars and buses each day.

...The bridge opened to pedestrians in December 1866, and the 1,057ft. main span was at that time the longest in the world, surpassing the Wheeling, WV suspension bridge (1849). Not only was the Cincinnati Suspension Bridge the world's longest, but it was also the first to utilize both vertical suspenders and diagonal stays fanning from either tower. This advance was next seen on the Brooklyn Bridge (also designed by John Roebling), which surpassed the Cincinnati bridge in length and almost every other statistical category in 1883.

Among the features of Letchworth State Park that attract attention and stand out in the memory bank of visitors of all ages is not part of the Park at all but is the Erie High Bridge. This railroad bridge is still in active use today, and is the same bridge, with some renovations to allow heavier trains, that was built after the equally famous wooden structure burned. The origin of this bridge leads us to study a very interesting man -- the engineer who designed the bridge, George Shattuck Morison. My reason for use of this title will become more clear as you read of his accomplishments.

An engineer by training, Eiffel founded and developed a company specializing in metal structural work, whose crowning achievement was the Eiffel Tower. He devoted the last thirty years of his life to his experimental research.

Born in Dijon in 1832, he graduated from the Ecole Centrale des Arts et Manufactures in 1855, the same year that Paris hosted the first world's Fair. He spent several years in the South West of France, where he supervized work on the great railway bridge in Bordeaux, and afterwards he set up in his own right in 1864 as a "constructor", that is, as a business specializing in metal structural work. His outstanding career as a constructor was marked by work on the Porto viaduct over the river Douro in 1876, the Garabit viaduct in 1884, Pest railway station in Hungary, the dome of the Nice observatory, and the ingenious structure of the Statue of Liberty. It culminated in 1889 with the Eiffel Tower.

John Roebling was enthusiastic.

"No other part of the East River offers a locality so favorable to bridging," the great engineer wrote to the New York businessmen who proposed building a span to link Manhattan and Long Island.

But the East River bridge that so interested Roebling was not the Brooklyn Bridge that would be the cornerstone of his enduring fame. This span -- proposed in 1856, more than a decade before the Brooklyn Bridge project took form in 1867 -- was what would become the Queensboro Bridge.

Upper Delaware Scenic and Recreational River is the home of the oldest existing wire suspension bridge in the United States — the Delaware Aqueduct, or Roebling Bridge as it is now known. Begun in 1847 as one of four suspension aqueducts on the Delaware and Hudson Canal, it was designed by and built under the supervision of John A. Roebling, future engineer of the Brooklyn Bridge.

Portions of the D & H Canal, including the Delaware Aqueduct, were designated a National Historic Landmark in 1968. The Delaware Aqueduct is also designated a National Civil Engineering Landmark.

...A German immigrant, and graduate of the Royal Polytechnic School of Berlin, Roebling came to the United States in 1831. It was not until 1845 that he built his first suspension structure. From 1845 until his death in 1869, he designed five major suspension bridges. Two — the Cincinnati-Covington Bridge and the Brooklyn Bridge — are still standing.

On June 12, 1806, John A. Roebling, civil engineer and designer of the Brooklyn Bridge, was born in Muehlhausen, Prussia. The Brooklyn Bridge, Roebling's greatest achievement, spans the East River to connect Manhattan with Brooklyn. For nearly a decade after its completion, the bridge, with a main span of 1595 feet, was the longest suspension bridge in the world. Steel wire cable, invented and manufactured by Roebling, made the structure possible.

When the Brooklyn Bridge was opened you had to pay three cents to cross it until it was paid for. When they opened the bridge everybody went to see it..It took them 14 years to build the Brooklyn bridge.

Villard de Honnecourt is known only through a portfolio of 33 parchment leaves containing approximately 250 drawings preserved in Paris (Bibl. nat. de France, MS. Fr. 19093). There is no record of him in any known contract, guild register, inscription, payment receipt, tax record, or any other type of evidence from which the names of medieval artisans are learnt. Villard's fame is due to the uniqueness of his drawings and 19th-century inventiveness in crediting him with having "erected churches throughout the length and breadth of Christendom" without any documentary evidence that he designed or built any church anywhere, or that he was in fact an architect.

Who Villard was, and what he did, must be postulated from his drawings and the textual addenda to them on 26 of the 66 surfaces of the 33 leaves remaining in his portfolio. In these sometimes enigmatic inscriptions Villard gave his name twice (Wilars dehonecort [fol. 1v]; Vilars dehoncort [fol. 15r]), but said nothing of his occupation and claimed not a single artistic creation or monument of any type. He addressed his portfolio, which he termed a "book," to no one in particular, saying (fol. 1v) that it contained "sound advice on the techniques of masonry and on the devices of carpentry . . . and the techniques of representation, its features as the discipline of geometry commands and instructs it."

As a father and son, John and Washington Roebling were the foremost American engineers of suspension bridge construction in the nineteenth century. John Roebling was born in Muhlhausen, Thuringia in 1806. While in school he developed an interest in both metaphysics and in bridge building. He graduated with a degree in civil engineering from the Royal Polytechnic Institute of Berlin in 1826.

In 1831 Roebling and his brother immigrated to Pennsylvania to farm. When this venture failed, Roebling accepted the position of Pennsylvania state engineer. In this position, he surveyed and supervised the construction of canals, locks, and dams.

In 1841 Roebling invented the twisted wire-rope cable, an invention which foreshadowed the use of wire cable supports for the decks of suspension bridges. Six years later he established a factory in New Jersey for the manufacture of this cable. Because the cable could support long spans and extremely heavy loads, Roebling quickly gained a reputation as a quality bridge engineer.

One of the foremost engineers and architects in the United States had connections with both North Carolina and Rowan County in the period between 1818 and 1840. His name was Ithiel Town, a Connecticut Yankee who was born in 1784, the son of a farmer.

As a youth he worked as a carpenter and taught school. Adventuring to Boston he acquired a knowledge of architecture under Asher Benjamin, an architect and prolific writer on the subject. While there he was chosen to make improvements on the State House at Boston.

His reputation was made in 1814 when he designed Center Church on the New Haven, Connecticut green. He later designed the state capitols in Indianapolis, Indiana and in Raleigh.

On January 28, 1820 he was granted a patent for a truss bridge and from that time forward he was the best known bridge builder in the country. His return from this work was greater than from his work as an architect. He published in 1821 a book on iron and wood bridges which became the bible for bridge-building in America.
