Streets, roads, and highways, at the very least, must meet , meaning coverage in multiple, reliable sources independent of the subject, in order to be worthy of a separate article.
Street and road maps, whether paper or online, may be used to verify the accuracy of information found within articles on streets, roads, or highways. For example, they show accurately where a road starts and ends, its junctions, and often landmarks along the road. It is also possible to determine a road's exact length using a computerized map system, and to provide a link to the results. While this information can and should be included in such an article, an article on a street or road should include more than just this information. If it is notable, more information will be available.
A single map cannot count as one of the sources used toward establishing notability. Maps of varying scales and from different years or decades can give a lot of information about a route. Using more than one map from different eras shows how a route has changed over time. Detailed maps, which can list every street, should be used sparingly; allowing a detailed map to establish notability would in theory render every side street as notable.
Published books (other than maps or directory-like publications) in most cases are considered a reliable source. Published non-map books that provide factual information about a particular street, road, or highway, such as its history, are valid in establishing notability.
Books used in establishing notability must provide in-depth coverage on the street or road in question. Trivial mention in a book itself does not help render a street notable. For example, if in a 200-page book, one sentence says "The boy walked down Oak Street" when this is the only mention of Oak Street in the book, this does not help render Oak Street as notable.
News reports about a road may help establish notability if they describe some permanence in the road. For example, news reports describing plans to build, expand, or permanently modify a road (or the outcome thereof), or telling about the road in how it relates to communities or landmarks along the road, are valid in establishing notability.
For example, the permanent closing of Pennsylvania Avenue around the White House, being sourced, is one of several factors contributing to Pennsylvania Avenue's notability as a street.
On the contrary, a temporary construction project that in the end does not alter the design of the street, but is only a routine repair or temporary road closure and detour, does not help render a street notable. Also, trivial information mentioned in the news (e.g. an accident or crime that just happened to occur on the street), even if these are multiple occurrences, is not noteworthy.
