Lewis Wernwag
Louis Wernag (December 4, 1769 in Alteburg, Württemberg, Germany – August 12, 1843 in Hapers Ferry, Virgnia) was a bridge builder in the United States in the early 19th century. Early life On leaving school, in order to evade military service, he was secreted by a shepherd in the mountains, who directed his attention to the study of astronomy, natural history, and other scientific subjects. In 1786, he made his way to Amsterdam and then to Philadelphia. United States His earliest venture in the United States was the building of a machine for making whetstones. Soon afterward he began to build power mills and bridges. While conducting this business he purchased land containing large quantities of white oak and pine timber in New Jersey, from which he got out, about 1809, the keel for the first U. S. frigate built at the Philadelphia Navy Yard. Bridges In 1810 he erected a bridge across Neshaminy Creek, on the road between Philadelphia and New York City. The following year ...

A View Of Fairmount And The Waterworks By John Rubens Smith 1835
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. At first, the B&O was located entirely in the state of Maryland; its original line extending from the port of Baltimore west to Sandy Hook, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River. Because of competition with the C&O Canal for trade with coal fields in western Maryland, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Port Deposit Bridge
The Port Deposit Bridge (also known as the Susquehanna River Bridge or Rock Run Toll Bridge) was the earliest bridge crossing of the Susquehanna River below Columbia, Pennsylvania, providing the first reliable link between the northern and southern United States. The bridge was also the fifth and last of Theodore Burr's Susquehanna crossings. The wooden covered bridge was constructed just north of Port Deposit, Maryland, between 1817 and 1818 and lasted until 1857. It was built and operated by the Susquehanna Bridge and Bank Company.

Theodore Burr
Theodore Burr (August 16, 1771 – November 22, 1822) was an inventor from Torrington, Connecticut, who was credited with the Burr Arch Truss bridge design. He designed and built one of the first bridges across the Hudson River and several bridges that crossed the Susquehanna River. Patent Burr was awarded US Patent No. 2769 on April 4, 1817 for his arch and truss bridge design. The "Burr arch truss" used two long arches, resting on the abutments on either end, that typically sandwiched a multiple kingpost structure. Theodore Burr built nearly every bridge that crossed the Susquehanna River from Binghamton, New York, to Maryland in the early 19th century. His successes made him the most distinguished architect of bridges in the country. Professional life Theodore Burr came to Oxford, New York in 1792. By 1794, he had built a grist mill (once owned by Fletcher & Corbin), and a dam to power the mill. In 1800, he built the first stringer bridge across the Chenango River in Oxf ...

Conowingo Bridge
Several incarnations of the Conowingo Bridge crossed the Susquehanna River at the original location of Conowingo, Maryland, United States, about two miles upstream of the Conowingo Dam, which replaced it. History The original Conowingo Bridge was a seven-span, , covered bridge built between 1818 and 1820 by Louis Wernwag, who also worked on the Rock Run Bridge. (Another source lists 1844.) That bridge was destroyed, in 1846 or 1847, by a flood. A new wooden covered bridge opened in 1859. This crossing was an important link between Maryland and northern states in the 19th century. During the American Civil War it was guarded on its southern approach and some of the bridge decking removed to prevent surreptitious crossing. On June 6, 1907, "firebugs" set fire to the 1859 bridge using kerosene. About three-quarters of a mile of it burned. The bridge was rebuilt as a steel structure in 1909. In 1911 the state of Maryland bought the bridge and ended the tolls. With the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
