street
A recognized road-vehicle corridor, including highways and accepted urban pedestrianized streets but excluding alleys.
A street is a transportation corridor for land vehicles. In special cases streets may be permanently closed to vehicles, but only in an urban setting where their identity as streets is commonly accepted. Highways are classified as streets, but alleys are not. Access ramps are streets but are not separate entities from the routes they feed.
The corridor can retain its street identity after permanent closure to vehicles in an urban setting. That exception concerns established recognition of the place as a street.
Highways are included in the stated broad scope, while alleys have a separate access role. Access ramps belong to the routes they feed rather than forming separate entities.
