Pittsburgh Streets

12th Street

Neighborhood: Strip District

The original name of 12th Street was O’Hara Street, after General James O’Hara (1752?–1819).[1, 4, 6] O’Hara Street first appears in William Darby’s 1815 map of Pittsburgh.[2]

In 1868, Pittsburgh’s modern sequence of numbered streets was created by renaming all the streets perpendicular to the Allegheny River; O’Hara Street became 12th Street.[1, 3, 5]

Today the name O’Hara refers to a different street, one in Oakland (see O’Hara Street).
