The
Autostrade (; singular ) are roads forming the
Italian national system of
motorways. The total length of the system is about 6,758 km. In North and Central Italy this is mainly as
tollways, with the biggest portion in concession to the
Atlantia group (
Autostrade per l'Italia) which operates some 3,408 km. Other operators include ASTM and ATP in the north-west, Serenissima and Autovie Venete in the north-east, SALT and Autocisa in the center, all under the control of the state-owned
ANAS.
