Pittsburgh Streets

49th Street

Neighborhood: Central Lawrenceville

The original name of 49th Street was Lothrop Street.[1]

In 1868, Pittsburgh’s modern sequence of numbered streets was created by renaming all the streets perpendicular to the Allegheny River; Lothrop Street became 49th Street.[2] The renaming ordinance actually says that it was Mill Street that became 49th,[3, 4] but this is off by one; see 43rd Street.
