"Oliver Evans, the Watt of America" Original portrait caption
Oliver Evans (September 13, 1755 – April 15, 1819) was an American inventor, engineer, and businessman born in rural Delaware and later rooted commercially in Philadelphia. He was one of the first Americans to build steam engines and an advocate of high-pressure steam (as opposed to low-pressure steam). A pioneer in the fields of automation, materials handling and steam power, Evans was one of the most prolific and influential inventors in the early years of the United States. He left behind a long series of accomplishments, most notably designing and building the first fully automated industrial process,first propose a design vapor-compression refrigeration, the first high-pressure steam engine, and the first (albeit crude) amphibious vehicle and American automobile.More recently, however, in the allocation of priorities for the development of the high-pressure steam engine, the simultaneity of Evans’ work with that of the British genius Richard Trevithick has been established, and historians have accorded proper credit for his pioneering of the assembly line.
Born in Newport, Delaware, Evans received little formal education and in his mid-teens was apprenticed to a wheelwright. Going into business with his brothers, he worked for over a decade designing, building and perfecting an automated mill with devices such as bucket chains and conveyor belts. In doing so Evans designed a continuous process of manufacturing that required no human labor. This novel concept would prove critical to the Industrial Revolution and the development of mass production. Later in life Evans turned his attention to steam power and built the first high-pressure steam engine in the United States in 1801, developing his design independently of Richard Trevithick, who built the first in the world a year earlier. Evans was a driving force in the development and adoption of high-pressure steam engines in the United States. Evans dreamed of building a steam-powered wagon and eventually constructing and running one in 1805. Known as the Oruktor Amphibolos, it was the first automobile in the country and the world's first amphibious vehicle, although it was too primitive to be a success as either. (Full article...)

What is now DE 273 was originally built as a state highway in the 1920s and 1930s, with the portion east of Hares Corner becoming a part of US 40, which had crossed the Delaware River on a ferry between New Castle and Pennsville, New Jersey. DE 273 was designated by 1936 to run from the Maryland border near Newark east to Hares Corner. In the 1950s, the route was extended east to New Castle when US 40 was realigned to the Delaware Memorial Bridge. DE 273 was moved onto new alignments around Christiana in the 1980s and through Ogletown in the 1990s. (Full article...)
