48th Street

48th Street
Neighborhood	Central Lawrenceville
Origin of name	Sequential numbering up the Allegheny River

Origin of name	Sawmill here on the Allegheny River
➤ 49th Street (1868–1868)
Origin of name	Sequential numbering up the Allegheny River, including Fisk Street

This street was originally named Mill Street for a sawmill on the Allegheny River between modern 47th and 48th Streets. R. E. McGowin's 1852 map shows that the sawmill was owned by Morrison & Wightman at that time; the 1862 map of S. N. and F. W. Beers shows that the mill was steam-powered; and by 1872 it was owned by Alexander McClintock.

In 1868, Pittsburgh's modern sequence of numbered streets was created by renaming all the streets perpendicular to the Allegheny River; Mill Street became 48th Street. The original renaming ordinance included Fisk Street in the list of streets to be renamed, which made Mill Street 49th, but this was apparently a mistake. Less than a month later, a supplementary ordinance repealed all of the name changes east of 40th Street and redid the numbering with Fisk Street omitted, which put Mill Street at 48th.
