Project:Rules of the game

From Pittsburgh Streets

Pittsburgh Streets is a long-term project. These are the rules and guidelines I aim to follow. They are written here mostly to help me stay on track and maintain consistency.


The scope of this project includes all named streets, avenues, ways, boulevards, lanes, roads, and so forth, that are wholly or partially within the current city limits of Pittsburgh, that exist today or have existed in the past or were seriously proposed (for example, "paper streets" that only ever existed on maps).

Public steps are in scope if they have a street name.

All streets entirely outside the current city limits of Pittsburgh are out of scope. If I do find an interesting piece of information about such a street, I may try to include it as an aside for a related Pittsburgh street (for instance, the former Llawnipsa Street in Aspinwall is mentioned in Aidyl Avenue).

Highways are in scope, but bridges and tunnels are not. For information about bridges and tunnels in Allegheny County, see Bruce S. Cridlebaugh, Bridges and Tunnels of Allegheny County and Pittsburgh, PA, 1999–2018 (

So-called "trap streets" are not in scope, if I can identify them as such. For example, the ninth edition of the Rand McNally Pittsburgh Street Guide shows "Querulous Street" at the western end of Kedron Street in Homewood West;[1] no such street has ever existed.

Article titles and disambiguation

Many Pittsburgh streets have had several different names over time, and similarly there are many street names (such as Washington Street) that have been applied to several different streets. This presents a challenge for organizing information about these streets: What title should the article about a particular street have?

The general principle is that the article about a street should use the most recent name of the street, with a disambiguator in parentheses if necessary. Former names of streets should redirect to the most recent name.

With very few exceptions (e.g., B Street), the current set of street names in Pittsburgh does not have duplicates. So nearly all streets that exist today will be found under their current names, with no disambiguator.

For a street that no longer exists, the article title should be the final name of the street. If that name has never been applied to any other street, no disambiguator is needed (e.g., Fancourt Street).

When a name has been applied to several different streets, disambiguation is necessary. Disambiguation of a name is done according to the following rules:

When it is necessary to use a disambiguator for an article title or redirect, it should be the first of the following options that is sufficient to disambiguate the name from other uses:

Some streets are officially divided into two streets with directional prefixes (e.g., North Negley Avenue and South Negley Avenue). For the purposes of this project, these are not considered to be distinct streets, and both are covered in the same article (Negley Avenue). But not all directional prefixes should be ignored. For example, these are completely different streets:

In some cases, the renaming of streets has changed what was once a single street into two or more streets, and it does not seem appropriate to redirect the former name to any single modern name. In such a case, a separate article is created for the former street, e.g., Main Street (Lincoln Place).


Pittsburgh Streets uses the official names and boundaries of Pittsburgh's 90 neighborhoods, as shown in the online Pittsburgh Neighborhoods map from the Department of City Planning.[2] These names and boundaries do not always match colloquial usage. For example, Carnegie Mellon University is often said to be in Oakland, but the majority of its campus is officially in Squirrel Hill North.

Citing sources

As far as possible, every statement should be supported by a reference to one or more sources. The sources should be specified in sufficient detail and precision that anyone can find the source and verify the statement.
