Brooklyn Bridge
The Brooklyn Bridge is a cable-stayed suspension bridge in New York City, spanning the East River between the boroughs of Manhattan and Brooklyn. Opened on May 24, 1883, the Brooklyn Bridge was the first fixed crossing of the East River. It was also the List of longest suspension bridge spans#History of longest suspension spans, longest suspension bridge in the world when opened, with a main span of and a deck above Mean High Water. The span was originally called the New York and Brooklyn Bridge or the East River Bridge but was officially renamed the Brooklyn Bridge in 1915. Proposals for a bridge connecting Manhattan and Brooklyn were first made in the early 19th century; these plans evolved into what is now the Brooklyn Bridge, designed by John A. Roebling. The project's chief engineer, his son Washington Roebling, contributed further design work, assisted by the latter's wife, Emily Warren Roebling. Construction started in 1870 and was overseen by the New York Bridge Comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cable-stayed Suspension Bridge
A cable-stayed suspension bridge or CSS bridge merges the designs of cable-stayed bridges and suspension bridges. The suspension bridge's architecture is better at handling the load in the middle of the bridge, while the cable stayed bridge is better suited to handle the load closest to the tower. Combining these two architectural engineering ideas into a hybrid has been done in Istanbul with the Yavuz Sultan Selim Bridge, and in New York City with the Brooklyn Bridge. A bridge over the Krishna River in India has been approved in October 2022 that will be a CSS bridge design. Yavuz Sultan Selim Bridge In Turkey the Yavuz Sultan Selim Bridge over the Bosporus Strait opened in August 2016. The main span is long and is the List of longest suspension bridge spans, 15th-longest bridge span in the world.

A National Historic Landmark District may include many contributing properties that are buildings, structures, sites or objects, and it may also include non-contributing properties. Contributing properties may or may not also be separately listed as NHLs or on the NRHP. History The origins of the first National Historic Landmark was a simple cedar post, placed by the Lewis and Clark Expedition on their 1804 outbound trek to the Pacific Ocean in commemoration of the death from natural causes of Sergeant Charles Floyd (e ...

Emily Warren Roebling
Emily Warren Roebling (September 23, 1843 – February 28, 1903) was an engineer known for her contributions over a period of more than 10 years to the completion of the Brooklyn Bridge after her husband Washington Roebling developed caisson disease (a.k.a. decompression disease) and became bedridden. She served as a liaison and supervisor of construction through communicating between her husband and on-site personnel. Her husband was the chief engineer during construction of the Brooklyn Bridge, which had been designed by his late father, John A. Roebling. Early life Emily was born on September 23, 1843, to Sylvanus and Phebe Warren at Cold Spring, New York. She was the second-youngest of twelve children. Emily's interest in pursuing education was supported by her older brother Major General Gouverneur K. Warren.

Washington Roebling
Washington Augustus Roebling (May 26, 1837 – July 21, 1926) was an American civil engineer who supervised the construction of the Brooklyn Bridge, designed by his father John A. Roebling. He served in the Union Army during the American Civil War as an officer at the Battle of Gettysburg. Education and military service The oldest son of Johanna (née Herting) and John A. Roebling, Washington was born in 1837 in Saxonburg, Pennsylvania, a town co-founded by his father and his uncle, Carl Roebling. His early schooling consisted of tutoring by Riedel and under Henne in Pittsburgh. He was sent to stay with Professor Lemuel Stephens of the Western University of Pennsylvania (now known as the University of Pittsburgh), where Roebling also attended some classes. Roebling eventually attended the Trenton Academy and acquired higher education in engineering at the Rensselaer Polytechnic Institute in Troy, New York, from 1854 to 1857.
