Delray Street

From Pittsburgh Streets
Delray Street
Neighborhood Central Business District
Origin of name Perhaps Delray, Michigan
Chancery Lane (1784 – ca. 1830)
Jail Alley (ca. 1790 – 1842)
Decatur Street (1842–1910)
Origin of name Stephen Decatur

This short street, between Fourth Avenue and Liberty Avenue just west of Market Square, was part of George Woods' original plan of Pittsburgh of 1784, though that plan did not give it a name.[1] In the 1830 map of Jean Barbeau and Lewis Keyon, it is labeled Jail Alley.[2] James M. Riddle's 1815 Pittsburgh directory lists "Chancery lane, (called in this work Jail alley)."[3] Chancery Lane (today Chancery Way) originally extended to Fourth Avenue (then Fourth Street), almost opposite Jail Alley, so apparently the two were originally viewed as parts of the same street.[4] Perhaps this is why Jail Alley is not labeled in Woods' 1784 map, though in Barbeau and Keyon's 1830 map the two are labeled separately. Jail Alley was so called because Pittsburgh's first jail was located there; it was a stone building, built about 1790, facing the Diamond (today's Market Square).[5][4][6][7][8]

Jail Alley was renamed Decatur Street in 1842.[9] It was probably named for Stephen Decatur (1779–1820).

In 1910, over 900 streets were renamed by a city ordinance to eliminate duplicates; Decatur Street was renamed Delray Street to avoid confusion with Decatur Street in Manchester on the North Side.[10] Like many of the new names introduced by this ordinance, the origin of Delray is obscure, beyond the fact that it begins with the same letter as Decatur. Perhaps it refers to Delray, Michigan, now a neighborhood of Detroit, which was an industrial city and the terminus of the Detroit, Toledo and Ironton Railroad. Compare Xenia Way, which may also have been named for an important railroad city.
