Line Street

Line Street got its name because it followed the final division line between the Cooper and Kaighn properties. Initially laid out as a twenty-foot alley, it was widened to fifty feet in 1848. That same year, when the city charter was amended by the State legislature, Line Street became the boundary between the Middle and South Wards, with Arch and Federal Streets marking the boundary between the Middle and North Wards.

Line Street should not be confused with Liney Ditch, also known as Little Newton Creek and Kaighn's Run, which served as the southern boundary of the South Ward. Over time, due to the encroachments of settlers and industrial progress, this stream began to fill up, becoming merely a ditch. Commonly called Line Ditch, it also marked the division between the lands of the Kaighn and Mickle families.
