|Origin of name||Sequential numbering up the Allegheny River|
The numbering of Pittsburgh's streets up the Allegheny River was done in 1868; these numbers extended as far as 50th Street. Today's 51st Street also existed at the time, as Cochran Street, but was apparently not given a number in 1868.
As additional streets were laid out in Upper Lawrenceville, there seems to have been some uncertainty about how they should be fit into the numbering scheme.
In 1873 another ordinance was passed to establish the location of 53rd Street: "Starting at a point of intersection of north side of Butler street and line of McCandless avenue, deflecting to right 10 deg. 8 min., running thence to Allegheny river, a width of sixty (60) feet." This description matches the part of McCandless Avenue north of Butler. Afterward it was apparently decided that this should just be part of McCandless Avenue, not a separately numbered street.
