On July 14, 1848 in Baku, Azerbaijan, Major Alekseev supervised the completion of a 20+ meter well, reaching a small pocket of crude oil, thus establishing the world’s very first oil well. The process used was an archaic technique known as cable-tool drilling, employed for hundreds of years in ancient China. Major Alekseev acted under the instruction of governor-general Mikhail Semyonovich Vorontsov, who in a memo wrote:

The Wheeling Suspension Bridge was the first bridge to span the Ohio River. It was initially completed in 1849, but destroyed by a tornado five years later. The bridge was rebuilt in 1856. The replacement bridge has the same general appearance of the original structure; the massive towers, anchorage housings, and island approach are all the original stone masonry.

The Delaware Aqueduct provided an important transportation link between the Pennsylvania's coalmines and New York's booming industrial marketplace. It is the earliest surviving work of John A. Roebling, who designed the Brooklyn Bridge  30 years later. The cable anchorage system first used on this project was also used on the Brooklyn Bridge. The aqueduct is patterned after Roebling's design of the Pennsylvania Canal over the Allegheny River, and is the oldest metal strand cable suspension bridge still standing in the U.S.
