An alley or alleyway is a narrow service road usually located between properties to provide access to back gardens, rear entrances, fire exits, and storage areas. Alleys are normally found in urban areas and often run between the rear sides of buildings such as houses, and commercial premises.
Old, narrow streets that provide access to the main entrances of buildings may also be mapped as alleys, distinguishing them from wider modern streets mapped, for example, as highway=residential. In some regions, this case is much more common than the rear access case.
Old or medieval ways
The very narrow old public streets which run in-between buildings in some settlements, such as the medieval European ones, often allowing through traffic, may be mapped using service=alley.

Alley streets are a road classification found in Baltimore, Maryland, USA, and potentially other places. Alley streets are alleys by definition, i.e., they serve the rear of buildings, but are named. Most named alley streets have addresses assigned to them, often small homes or carriage-houses that have been converted into homes, due to Next Generation 911 (NG911) standards that require local governments to sign any public street with addresses. Alley streets may have sidewalks but they are small and designed to house trash cans or steps down from homes. Alley streets do not typically have on-street parking, which distinguishes them from residential streets.
