Ackley Bridge is an excellent example of a multiple kingpost truss and a noteworthy early example of covered bridge preservation efforts in the United States. Built in 1832 by Joshua Ackley (b.1805) and Daniel Clouse (b.1812), Ackley Bridge originally spanned Enslow’s Branch of Wheeling Creek between Greene County and Washington County in Pennsylvania, where it carried traffic for over a century.

In January 1838, Samuel F. B. Morse and Alfred Vail first demonstrated publicly crucial elements of their telegraph system, using instruments that Vail had constructed during the previous months. Electrical pulses, transmitted through two miles of wire, caused an electromagnet to ink dots and dashes (grouped to represent letters and words) on a strip of paper. Commercialization began in 1844 when funding became available.

A pioneer in the development of electrical science, Nicholas Joseph Callan was born on 22 December 1799 in Darver, Ireland. He started the priesthood at Navan Seminary, and continued his studies at St. Patrick’s College Maynooth, where he studied natural and experimental philosophy under Dr. Cornelius Denvir. After his ordination as priest in 1823, Callan pursued his doctorate in divinity in Rome, where he became acquainted with Galvani and Volta’s work in the study of electricity, and recognized the potential to put it to practical and commercial use with powerful batteries.

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.
