Porta Ardeatina in
Rome, an urban strada comunale classified as
strada urbana di scorrimento. region marked with a number and with the abbreviation SC. Very rarely extra-urban strade comunali are marked with a number and with the abbreviation SC. Strade comunali within inhabited centers can be classified from a construction-technical point of view either as urban roads (type D and E) or as local roads (type F). Extra-urban municipal roads (outside inhabited centers) can be technically classified as
strade extraurbane principali (type B; "main extra-urban roads"),
strade extraurbane secondarie (type C; "secondary extra-urban roads"),
strade urbane di scorrimento (type D; "urban traffic roads") or
strada locale (type F; local roads). Assuming that the urban roads within the inhabited centers are all owned by the municipality (with the exception of the internal sections of state, regional or provincial roads that pass through inhabited centers with a population not exceeding 10,000 inhabitants), it is understood that the extra-urban roads outside the inhabited centers are to be considered municipal when: • they connect the capital of the municipality with its hamlets or join the hamlets together; • they connect the capital of the municipality with the railway, tram or car station, with an airport or sea, lake or river port, with interports or intermodal exchange nodes or with the localities that are home to essential services of interest to the municipal community; • they belong to state property (see State Archive of State Property) or if acquired with an act of expropriation of private land (see City Council Resolution). The useful elements to assume that a road is municipal property are: its location within the inhabited centres, its name in the toponymy and consequently in the cadastral maps, its house numbering, presence of lighting and water collection, be constantly maintained by the municipal body. ==Nomenclature==
