The Autostrada A20 is an autostrada (Italian for "motorway") 183 kilometres (114 mi) long in Italy on the island of Sicily that links the city of Messina to Termini Imerese.

The motorway from Messina follows the Tyrrhenian coast until it meets the A19 Palermo-Catania at Buonfornello, a frazione of Termini Imerese.

Consorzio per le Autostrade Siciliane is in charge of toll collection, management, and maintenance of the motorway.

[1] The construction of the A20 was really slow, partially because of the difficult orography of the Tyrrhenian coast.

The first stretch of this motorway, from Messina Boccetta to Divieto, was opened the 1 June 1972[2] but works for the entire length were completed only the 21 July 2005 with the opening of the exit for Castelbuono.
